[HOU-2379] CUDA Multitext Error

[hsz]

When you use the multitex on CUDA I'm getting this weird artifact as you can see the CPU does not have this issue.

This happens with Vray 5.0.50 and Today's nightly 11124

Hey hsz ,

Thank you for the heads up. I've logged the issue in our tracker and will inform you as soon as we've made progress.

Meanwhile, a possible workaround I could suggest is to pack the geometry based on the "id" attribute - you can then rename it to "vray_objectID" and use the "Object ID" option on the Multi ID texture. I understand it's not ideal - I'm suggesting this in case the issue is blocking you at the moment. I've attached an example here: https://drive.google.com/file/d/1uVt...ew?usp=sharing

Hope that helps!

Thank you for the workaround - I'll use this until this get fixed properly, cheers.
