Title: About UV
Post by: SL7359 on August 01, 2022, 11:51:36 AM

For UV, the results are different when rendered with V-RayGPU and when rendered with V-RayCPU.
Where can I find the cause of these differences?
Is it possible to match the CPU results?

Try to turn off the instancing engine.

That's it. For V-Ray CPU we can generate and modify UVs of instances at render time.
But this is not possible for other renderers (including V-Ray GPU), because the engine is not open for third-party plugins.

Thank you for your response. Resolved.
It is a different scene, but when I disable the instance engine, the textures are not reflected.
What could be the cause of this?

You must apply the material to the RC object.

'Use Segment Material' has no effect when instancing engine is disabled.
Basically when instancing is off, RC generates a standard mesh, as any other Max object (which needs some material).
