User color attribute on GPU/RTX for instances(Packed primitives).

[koncepd]

Hello, I'm working with packed primitives and trying to use for example @Cd attribute to drive a color change in the material builder using User-Color node. It works flawlessly with CPU but gets completely removed from calculation in RTX/GPU mode (and hybrid as well).

Is this a bug or something that's not implemented yet? Are there any workarounds?

Thanks in advance!

Hello koncepd , I've reproduced the issue and reported it. Will write back when it is fixed.

Thanks a lot!

Heya it seems like we are having the issue where we can't use User Color attrs on a particle system with RTX/CUDA. Is this related or the same issue?

Thanks!
