Title: Rug rendering
Post by: pjividen on 2025-06-16, 18:01:32
Hello All,

I've been trying to troubleshoot the best method of recreating this multi-pile rug design pattern. I have used a variation of methods: corona displacement modifier, and Hair and fur modifier and haven't had any great results. Help would be appreciated!

 see attached reference.

Forest Pack (or Corona Scatter) using a map to drive the height?

I created uv custom map that I placed in the the Surface scattering tab, but appears to bunch up the fibers vs creating a height difference.
Do you know where I would place the map to control the height?


Best,

Phillip

I don't use Chaos scatter but you want to be looking for a Scale option in particular the Z axis

You can use a map to drive instance height. Tooltip under the "map" says that blue is for Z axis, so we need that.

Alternatively, you could use the new Scatter feature Clusters > Instance color to map. This way you can scatter taller strands on color 1 and shorter strands on color 2.

You can also look at feature to simulate bent strands under tables, chairs and other objects. Chaos Scatter is becoming really versatile tool.

can I ask what method you used to model the rug strands/clusters?   I just instanced a cylinder and obviously looks more like sandpaper than carpet.
