00:00Hello everyone, welcome back to the channel Web4Click
00:03and today we are going to talk about Decimate Modifier
00:06So without wasting any time, let's get started
00:09First of all, I am going to delete these
00:11To explain Decimate Modifier, first of all, I am going to take a UV Sphere
00:16I am going to enlarge the UV Sphere
00:19I am going to press the Home button and take it in focus
00:21and on the top side, I am going to do the same
00:25Now we are going to apply Decimate Modifier
00:29As soon as I use Decimate Modifier, a window will appear in front of me
00:34In this, you will get three options
00:36Collapse, Unsubdivide and Planner
00:39Also, you will get a Ratio option here
00:41in which 1 is written
00:43We can increase or decrease it between 0 and 1
00:46If I try to reduce it by holding this Ratio option
00:49then you will see that my modifier will gradually decrease here
00:55and in the end, it will remain as a plane
00:58If we bring a cursor on it, then it is clearly written that
01:01Use Age Collapsing
01:03Collapse in Hindi means to shrink anything
01:07and Age Collapsing is written here
01:09it means that its ages will gradually shrink here
01:13with the help of Ratio
01:14and in the end, it will become a plane
01:17So the work of Decimate Modifier is to shrink any object here
01:23I have already told you that
01:25We should be able to control anything
01:27and we should know where that option is used
01:31only then we can use it properly
01:34Otherwise, that option will remain as an option for us
01:37and we can never use it
01:39So first of all, let's see where Decimate is used
01:44So here you can see that I have a scene
01:47in which a lot of Decimate has been used
01:50In this, you can see that I have a lot of trees
01:54and there is a house as well
01:56and there are clouds on the top side as well
01:58If you look at them carefully
02:00then you will see something like this
02:03You can see small triangles here
02:06It means that it has been shrunk
02:09When we Decimate it
02:12then this kind of option comes to us
02:15and all the scenes that we will make here
02:18are all made with the help of Decimate
02:20If you look at its mountain
02:22then you can see how many pointed stones are visible here
02:26and there are also small stones on top
02:29and these stones have also been made with the help of Decimate
02:33So wherever we need to make such a scene
02:36Decimate is very useful in that
02:39So let's understand Decimate in detail first
02:42After that, we will make a tree like this
02:45as this tree is present here
02:48So we are back on our Blender screen
02:51In these three, the first option is Collapse
02:54Second is Unsubdivide and the third is Planner
02:56We will understand these three in detail one by one
02:59First, let's understand all the options of Collapse
03:01In this, the first option I have is Ratio
03:04I have already told you about Ratio
03:06With the help of this, we can pull it down or increase it
03:09and as soon as I decrease it
03:11my faces will start shrinking
03:13and it will shrink and come to me as a small plane
03:18You can see the count of how many faces are increasing and decreasing
03:23So this is a simple option I have
03:25which I can use here, Ratio
03:28Next option is Symmetry
03:31In Hindi, Symmetry means Samrupta
03:34As soon as I tick it, three axes will be visible here
03:38You can see, I can select any of these axes by clicking on it
03:42Right now, it is on the X-axis
03:44So globally, our X-axis is the red line
03:47If we want to see this object in Symmetry form
03:50For that, I will delete it from here
03:52and to make you understand, I will take a Mirror modifier from here
03:56With the help of Mirror modifier, we can make any object in another form
04:00as we can see in CC
04:03I have already told you about Mirror
04:05In episode 24, I used Mirror in the character
04:09You can see it there
04:11Right now, I have applied it here
04:14If I want to mirror another object of this object
04:17First of all, I have to go to Edit mode
04:20If I move it back and forth, you can see
04:22There is no mirroring here
04:25The reason for this is
04:26My origin point is at one place
04:30and it moves with this object in Object mode
04:34But as soon as I go to Edit mode
04:36and if I simply drag it to the back side
04:40As you can see, my other object will be mirrored here
04:44Both of these objects are same
04:46and as soon as I come out of the tab
04:48Now, I have these two objects
04:50But both of them are interlinked
04:52and I have only one object here
04:55Just to make you understand, I have mirrored it
04:57Both of them are the same object
04:59Now, I will apply Decimate modifier
05:02First of all, I will click on Symmetry
05:04and in this, you can see on the X-axis
05:06Right now, I have taken a duplicate of it on the red line
05:09Whatever changes are going to happen in this
05:11If I want to see it properly
05:13I have an option of View Overlay
05:15In this, I will get an option of Geometry
05:17If I click here and turn on Wireframe
05:20Now, my faces will be highlighted here
05:23and as they are more or less
05:25I will be able to see them properly
05:27Now, I have selected the X-axis here
05:29and as soon as I will reduce it here
05:32You will see that both are changing in the same way in front of me
05:36Whatever changes are happening in this
05:38The same changes are happening in the other side
05:40in the other object
05:42and as I will reduce it slowly
05:44In the end, both of them will become a plane
05:47As soon as I will increase it
05:49You can see that both of them are in the same way
05:52So, we can use Symmetry here
05:54Whenever we want to change the same geometry on the X-axis
05:58We can change it in this way
06:01For now, you have seen that on the X-axis
06:03Both of them are changing in the same way
06:06But if I select Y from here
06:08Now, they will not work in the same way
06:10They will work in different ways
06:12and both of them will have different geometries
06:17In the end, if I will show it to you
06:20So, you can see that the geometry of the last one
06:23is completely different
06:25I will move it to the front side
06:27So, you can see that the geometry of the last one
06:30is completely different
06:34Similarly, if I will select Z
06:36So, the geometry has changed again
06:38and here also
06:40Both of them have different shapes
06:42It will be reduced slowly
06:44As soon as I will increase it
06:46Both of them will go in the full mode
06:48and you can see that
06:50Both of them are changing in different ways
06:53Only on the X-axis
06:55This geometry will work
06:57Because it is on the X-axis
06:59And as soon as I will reduce it
07:01You can see that
07:03Both of them are working in the same way
07:07And in the end
07:09Both of them will be in the same plane
07:13Because they are opposite to each other
07:15That's why it is on the lower side
07:18So, we can use symmetry in this way
07:21If these two objects are on the Y-axis
07:23Then we will click on Y
07:25And both of them will be on the Y-axis
07:27In the same way
07:29They will be modified and will be reduced
07:31For now, I will complete it
07:33So, this was our symmetry modifier
07:35The third option is
07:37Triangulate
07:39If I will click on Triangulate
07:41And now I will reduce it
07:43So, my faces in the form of square
07:45will start reducing here
07:49And most of all, this triangle will be created here
07:52And in the form of triangle
07:54It will start reducing
07:56So, whenever we need more triangle
07:58We can click on Triangular
08:00And reduce it
08:02And wherever we need shape
08:04We can leave it
08:06So, in the form of triangle
08:08We can reduce it more or less
08:10So, you must have understood
08:12Triangular
08:14For now, I will delete it
08:16Again, I will take an object
08:18UV Sphere
08:20I will scale it and increase it
08:22I will bring the home button in focus
08:24Again, I will apply
08:26Decimate modifier
08:28Let's move ahead
08:30Next option is Vertex Group
08:32I have already told you about vertex group
08:34You can see it in my
08:36Bevel modifier class
08:38For now,
08:40We will check the vertex
08:42How it works
08:44If I click on vertex
08:46You can see there is no group here
08:48It is empty
08:50If we want to create vertex group
08:52We have to go to
08:54Object Data Properties
08:56As soon as I click on
08:58Object Data Properties
09:00Vertex group will appear
09:02And I can create group
09:04By clicking on it
09:06First, I have to go to edit mode
09:08And I can create group
09:10Of all the faces
09:12For now, I will select all the faces
09:14I will press Alt
09:16I will press Ctrl
09:18I will select all the faces
09:20You can see
09:22I have created a group
09:24For this group, I will click on vertex
09:26And I will name it
09:28Top
09:30As soon as I click on assign
09:32My group is assigned
09:34And I have a vertex group
09:36Let's go back to object mode
09:38And as soon as we go to modifier
09:40This time, my vertex group
09:42Will highlight an option
09:44As soon as I select this top
09:46This time, only the
09:48Group that I have created
09:50That group will be decimated
09:52The remaining portion
09:54Will not be decimated
09:56And as soon as I try to reduce it
09:58You can see, only that much area
10:00Is being decimated as much as I need
10:02The lower part is
10:04Like this
10:06So, in this way, you can use
10:08Vertex group
10:10You can use it wherever you need
10:12So, I will complete it again
10:14And let's go ahead
10:16First of all, I will tell you
10:18That you will see a small option
10:20In the corner of arrow
10:22This is our reverse option
10:24Or we call it
10:26Invert option
10:28If I click on it, it will be blue
10:30And whatever group
10:32I selected here
10:34Apart from that, the remaining portion
10:36Will be changed here
10:38Because my vertex group
10:40Has been inverted
10:42Now, if I reduce it
10:44You will see that all the options
10:46Will be reduced
10:48And all the faces below
10:50Will be reduced
10:52In this way, if you want to
10:54Create any shape
10:56You can decimate the lower part
10:58In this way
11:00Diamond shape or many other
11:02Shapes can be created with the help of this
11:04I will remove the invert option
11:06From here
11:08And the upper part
11:10Where the vertex group is applied
11:12Only that part will be covered
11:14So, in this way, you can use vertex
11:16You can also use it by inverting
11:18There is an option below
11:20Of factor
11:22The more you increase it
11:24The faster it will
11:26Increase the ratio
11:28So, whenever we make a video in detail
11:30Then we will know it in more detail
11:32For now, the vertex group
11:34You must have understood
11:36So, we use it here
11:38For now, I delete it
11:40And again
11:42I take an object here
11:44And increase it by scaling
11:46By pressing the home button
11:48I will bring it in focus
11:50Again, I will use decimate modifier
11:52Now, we saw
11:54All the options of collapse
11:56How they work
11:58So, let's make a small example of collapse
12:00To understand collapse
12:02In a better way
12:04Let's make a tree like this
12:06And see how
12:08We will use decimate
12:10So, let's start
12:12Again, we are on the blender screen
12:14Now, I don't need this modifier
12:16So, I delete it
12:18I have one here
12:20UV sphere
12:22To make a tree, we can take anything
12:24UV sphere, if we want
12:26We can make a tree from UV sphere
12:28Let's go to edit mode
12:30And from here, I click on the vertices
12:32I highlight all the vertices
12:34If I want to merge
12:36All the vertices
12:38For that, I select all
12:40Right click
12:42And here, I have an option
12:44Merge vertices
12:46In this, where you want to merge the vertices
12:48At the center
12:50It will merge
12:52Or at the cursor
12:54For now, I merge it at the center
12:56So, you can see
12:58Where my 3D cursor was
13:00Here, it merged it
13:02I have only one vertex left
13:04Or we can say
13:06There is an origin point
13:08From this origin point, we will make a tree
13:10Let's see how
13:12If I want to move this vertices up
13:14I will press E
13:16And in Z direction
13:18I will move it up
13:20So, I can move it as much as I want
13:22First of all, we make branches
13:24So, we turn one branch
13:26To this side
13:28I will press E again
13:30And this time, I will move it
13:32To the Y axis
13:34And by pressing E
13:36I will move it to the front
13:38Again, I will press E
13:40And randomly
13:42By pressing E
13:44I will move it as much as I want
13:46I will select it again
13:48I will press E again
13:50And in Z direction
13:52I will move it up
13:54This time, I will remove the branches
13:56I will press E again
13:58And in Y direction
14:00I will move it to this side
14:02Again, I will press E
14:04And I will move it up
14:06Again, I will press E
14:08And without any button
14:10I will move it to this side
14:12In one branch
14:14I will select it
14:16I will press E
14:18And in Z direction
14:20I will move it up
14:22Again, I will press E
14:24And I will select it randomly
14:26Again, I will press E
14:28And I will move it up
14:30In this way, you can make branches
14:32You can make as many branches as you want
14:34Again, I will press E
14:36And I will move it up
14:38In Z direction
14:40And from the top
14:42You can see that my branches are here
14:44So, I will move one branch to this side
14:46By pressing E
14:48I will move it to this side
14:50Again, I will press E
14:52And I will move it to this side
14:54By pressing E
14:56I will move it up
14:58In Z direction
15:00Now, you can see that
15:02I have branches of trees
15:04We will make a tree from them
15:06By pressing tab
15:08I will go back to object mode
15:10I will click on it
15:12I will right click
15:14And I will get an option here
15:16Convert to curves
15:18First of all, I will convert it to curves
15:20You can see that
15:22I have an option here
15:24Now, my first mesh
15:26Has become a curve
15:28I will press shift A
15:30You can see all these options
15:32These are my mesh options
15:34And you can see that
15:36Curve is a line
15:38Which is made up of vertices
15:40And mesh is made up of vertices
15:42And faces
15:44So, in this way, I have a curve
15:46Or we can take any curve
15:48And whatever I am going to do next
15:50We can use it in this way
15:52Now, my main work is
15:54To make a mesh
15:56How we will make that mesh
15:58Let's see
16:00I will select it here
16:02Now, you can see that I have converted it to curves
16:04After converting it to curves
16:06I will get an option here
16:08Which is named
16:10Object data property
16:12Earlier, it came in triangle shape
16:14But when I clicked on curve
16:16It has changed
16:18There are many options
16:20Which we will know in detail
16:22When we will do a curve class
16:24You can see curves here
16:26We will do a curve class
16:28For now, I will do what I need
16:30First of all, I have to make a mesh
16:32To make a mesh, I will go here
16:34I will get a geometry option
16:36First of all, you will get offset and extrude
16:38But at the bottom, I have an option
16:40Of bevel
16:42This bevel will work here
16:44This bevel will work here
16:46The first option is depth
16:48So, from this depth, I can decide
16:50How much thickness I want to keep
16:52You can see that
16:54I can make a bevel
16:56I can make a mesh
16:58As I click on it
17:00Its size will increase
17:02Whatever size you want
17:04You can click on it
17:06For now, I will keep this much
17:08You can see that it is open
17:10If I want to close it
17:12I will click on fill caps
17:14As soon as I click on fill caps
17:16It will close
17:18If you want to improve the mesh
17:20You can click on resolution
17:22I can click on it
17:24I can add more faces
17:26I can smooth it
17:28Now, I don't have to do anything
17:30If you want to scale it
17:32You can do it by tapping on it
17:34Here, I will make the thickness
17:36Thicker
17:38As soon as I convert it into a curve
17:40You can see that my options are changed
17:42The vertices and faces
17:44Which were there before
17:46Are not there
17:48The reason is that
17:50It is converted into a curve
17:52With the help of vertices
17:54I can change it
17:56If I want to reduce this
17:58I will select it
18:00I will press S with ALT
18:02I can make it thinner
18:04You can select the area
18:06And press S with ALT
18:08In this way
18:10I will make the vertices
18:12Thinner with S with ALT
18:14If I want to make it
18:16Thinner
18:18I can increase it
18:20In Z direction
18:22I will select all of them
18:24By pressing SHIFT
18:26I will press S with ALT
18:28I will make it thinner
18:30You can manage it in this way
18:32You can select the portion
18:34You want
18:36I will press S with ALT
18:38I will make it thinner
18:40In this way
18:42I will press S with ALT
18:44I will make it thinner
18:46If I want to make it thinner
18:48I can make it thinner with S with ALT
18:50The lowest part
18:52I will increase it
18:54With S with ALT
18:56So that it looks like a tree
18:58I will increase it
19:00With S with ALT
19:02After managing it
19:04I will come to object mode
19:06You can see
19:08How it looks
19:10I will close the wireframe
19:12And go back to material mode
19:14And give some material
19:16The color of the tree
19:18I will assign the material
19:20And from here
19:22I will make it black
19:24So that it gets a color
19:26If I want to make the leaves
19:28I will press SHIFT A
19:30And select a UV sphere
19:32I will place it on the top
19:34I will scale it
19:36I will select it
19:38And place it on the top
19:40And scale it
19:42I will press SHIFT D
19:44I will take a leaf
19:46From the other side of the tree
19:48I will make it smaller
19:50So that I can see
19:52The difference
19:54I will scale it
19:56I will press SHIFT D
19:58And place it on the bottom
20:00I will scale it
20:02And place it on the top
20:04I will press SHIFT D
20:06And place it on the top
20:08I will scale it
20:10And place it on the top
20:12Like this
20:14My tree is ready
20:16But it doesn't look like
20:18A particular tree
20:20I will scale it
20:22It looks weird
20:24I will assign a color
20:26I will select one
20:28I will assign a green color
20:30If I want to apply the same color
20:32To all the objects
20:34I will select all
20:36I will select the last color
20:38I will press CTRL L
20:40I will get an option
20:42Link materials
20:44I will click on link materials
20:46All the materials
20:48Will be applied to the objects
20:50And in whichever
20:52Object I change
20:54It will change automatically
20:56Like this
20:58You can apply to all the objects
21:00Now you can see
21:02My tree doesn't look like
21:04A particular tree
21:06First we will decimate it
21:08So that it looks good
21:10Let's go to the decimate modifier
21:12Let's go to the decimate modifier
21:14I will apply it on one leaf
21:16If you want to triangulate
21:18Click on it
21:20And when I decrease it
21:22You will see
21:24I can decimate it
21:26As much as I want
21:28For now I will keep it
21:30And when I will apply it
21:32It will be applied
21:34To all the objects
21:36If I want to apply
21:38To all the leaves
21:40I will select all
21:42I will select the last
21:44I will select the last
21:46I will press CTRL L
21:48I will get an option
21:50Link object data
21:52It will change automatically
21:54If I want to
21:56Decimate it
21:58I can do it as per my choice
22:00For now I think
22:02This leaf is too small
22:04So I will increase it
22:06Let's go to the
22:08Edit mode
22:10I will extrude it
22:12By pressing E
22:14In Z direction
22:16Now I will select it
22:18And press ALT S
22:20I will increase it
22:22I will press ALT S
22:24And change it
22:26One important thing
22:28In curve option
22:30I will scale it by ALT S
22:32Now you can see
22:34How my tree
22:36Has changed
22:38And how good it is
22:40If you want to
22:42Decimate it
22:44You can do it
22:46I will decimate it
22:48Now you can see
22:50How good it is
22:52I will select it and apply it
22:54As soon as I apply it
22:56You can see
22:58It doesn't work with curve
23:00So first of all
23:02I will remove this modifier
23:04And convert it to mesh
23:06Convert to mesh
23:08Again it will convert to faces and edges
23:10And from here
23:12I will click on decimate
23:14And I can decimate it
23:16I will do this much portion
23:18So that I can see it
23:20Properly
23:22And from here I will apply it
23:24And it will be applied
23:26Like this my tree has been created
23:28You also practice it
23:30With this you will know
23:32How my collapse option
23:34Will work
23:36So in today's video we have understood
23:38Collapse option of decimate
23:40And explained in detail
23:42How all the options work
23:44Also made an example
23:46How we apply collapse
23:48Here
23:50Now we have two options
23:52Unsubdivide and Planner
23:54Without making this video too long
23:56Let's end it here
23:58Unsubdivide and Planner
24:00We will understand in detail
24:02And the second part of decimate
24:04I will cover in the next video
24:06You don't have to wait too much
24:08For the next video
24:10I will upload it as soon as possible
24:12So let's meet in the next video
24:14Till then goodbye
