[HOU-1904] VRay Dirt result differences in IPR vs Bucket

[david.anastacio]

Hi,

There seems to be an issue with the VRay Dirt calculation in IPR mode, the result is quite different when rendered in bucket mode,. This is quite bad, after spending a couple of hours building shaders only using the IPR, I find out my shaders look completly off when rendered in bucket mode....
Example image and test scene attached.

The result is very dim in IPR:


Best,

Hello david.anastacio , the behavior is similar to the issue with baked blend material, looks like dirt+curve are causing it. I'll dig a bit more and will report it.

I was thinking they might be related too. Thanks for looking into it.

Best,
David.

Heyyy

chakarov, is there any update/progress on this issue here?
I tested this with the latest nightlie and it seems the issue is kind of minimised but still there:



Also, the bucket render looks different with the latest nightlie compared to the render from 3 months ago, I used the same exact test file I sent you before, why is this different now? This should not happen, as this will change the look of shaders and renders.

Best,
David.
