Hi
Don't know if this is a bug or user error, but the Cloth Surface generator doesn't respect the Color Shader I've applied to the child Cloner object.
I was trying to create the windows 11 background using a cloner and some cloth discs, but the shader doesn't work with the Cloth Surface generator.

If you toggle on and off the Cloth Surface generator in the attached file you'll see the problem.

This is using C4D 2024.4.0 and Octane 2023.1.2-(R7)

Cheers

Hi,
try to make the Cloth Surface parent of the disk, not of the Cloner:

Thanks Beppe.
It works, but sadly doesn't let you alter the Cloth subdivision after the sym is cached. Oh well.

Use an Octane Object Tag and set your subdivision with that instead. It will add SubDs at rendertime on the GPU.

Hi,
the issue is that the Disk topology is not good for deformations, but you can use a Remesh tool to have a perfect quad mesh that doeesn't have issues in deforming:

Thanks guys.
#jayroth2020 The Cloth generator is also providing thickness to the geometry, which the Octane Object tag doesn't provide.
#beppe The disc has a non-zero internal diameter, so the geometry is all quads already. Unless C4D is doing something internally that isn't displayed.

You can still use the Octane Object tag for your Subdivision; just disable the sudivision on the Cloth Generator...

It's more about the Color Shader node not randomising the colour once the Cloner is put under the Cloth Generator, rather than a subdivision issue.
Somewhat resolved the problem by using a Tube object, with an Octane Object Tag for the subdivision. The sim runs slower, which is a pain, but it gets what I want.
