BETTER PERFORMANCE in Blender with the Decimate Modifier!

In this video, learn to use the decimate modifier for Blender to reduce the size and complexity of objects to improve performance!
Often, we'll use models inside of Blender that are just too complex - they have way more faces and vertices than they really need, which can really hurt your model performance on your computer.
This modifier gives you an easy way to reduce the number of edges/faces/vertices in your model!

Great video and tutorial. I think im winner of all sub problems 😂 I make mushroom and sub it 2 times i copy it i 6 mushrooms and make colection,that colection i copy 15 times and that 15 times i copy 3 more.times.. 3x45 + x6 more mushrooms ..810 copied mushrooms with sub lv 2 when i opet decimate modf it was in 1 colection over 4 mil faces and i got 3 colection,that was 12mil faces my pc crash and blender 😂

It was really helpful. It was exactly what I was looking for. I wanted to upload a model to Pepacura to make a real 3D sculpture and the only way to do it was to decimate my model to get way fewer faces. Thank you, man.

For game models to get the most optimal results use planar, with the option that preserves your uv seams. Then select an angle that gives you an acceptable amount of detail. Place a triangulate modifier after.

I notice every time I need some Blender info I end up coming back to you. Concise and clear, thank you. I was panicking about what I was going to do with my model that caused Blender to slow down severely. I used the decimate modifier and brought it down where it still looked good. Now I can even use duplicates of the object in my scene. Thank you, thank you, thank you!!!

Do you not know who frecken helpful this is! Dude thank you!

So thank you! Now my computer runs easier and faster, truly thank you!

@LisaMurphy
@LisaMurphy 2 года назад
So I notice that when I go into edit mode to delete some things all the original vertices show up again. It makes me wonder. So all of the original geometry is still there, so what is really being accomplished with decimate? Does this mean the rendering will go much faster? As far as just working with the environment in the layout mode, I don't really see a difference in performance. I hope it does help in rendering time.

Thanks for posting this tutorial on the Decimate Modifier. I notice you joined all the objects before using the modifier. Is it possible to apply the modifier to different, unjoined meshes? For instance, a Decimate Mod for the horse's mane and a separate modifier for the robes, resulting in a reduced edge count for the densest part of the mesh.
@TheCGEssentials
@TheCGEssentials 3 года назад
Sure - they just get applied to the individual meshes as you add the modifier - not sure how they'd look when they run into each other

@fabiansantiago93 2 года назад
Wow thank u very much this save me a lot of time. I am using blender to import models to a lighting software so with lower poligons it makes the calculation so much faster. Also I have a question is there a site where I can find simple 3d models already made, like chairs, tables, trees, display furniture for shops?

I use decimate often when I bring in models from Adobe medium. It’s a massive struggle to retain what looks like simple geo for some mud brick looking houses I am making for some villages. But when I decimate. To get even simple looking meshes of homes down below 500k polys homes always start to look like melted butter. It like the trade of for voxel work is either work small or have a scene that looks like melted butter. I wish decimate kept hard edges

@bitsurface5654 3 года назад
You will get small (black) triangles when you do this. This is due to the UV map which is also reduced, and blender do not know where to take the texture from. It is also good to have two (objects) of them an rebake the Texture from hi to low poly so you can get rid of the black triangles.

can i have the Decimate object in the Edit mode? I mean when i have a model with many tris and would like to reduce them with this modifier. Can I somehow bring the result into edit mode so that I can edit it further manually? Because if I go after the video and then switch to edit mode, in edit mode it has the original model (with the original amount of tris) and only in object mode does it have the reduced tris that I reduced with the Decimate modifier.

I have a question however I am unsure what exactly to ask for when going on public forums, for example I have some models I've ripped from old games I used to play and wanted to do some non textured Blender art but the only way I can make the rips/meshes look really nice was to use the flat shade thing and now there's a bunch of individual flat faces/edges or whatever it's pronounced and I have no clue how to keep the overal amazing look but making the edges/faces flat/smooth it's weird I guess.
