Added support for UVWGenRandomizer - same as VrayUVWRandomizer?

[lightwriter]

Hi there!

I noticed that in this new version there is support for UVWGenRandomizer. Is this the same as the V-ray map VRayUVWRandomizer, present in the v-ray 5 version of 3ds max?

Hi lightwriter

Yes, the UVWGenRandomizer is the V-Ray map VRayUVWRandomizer from V-Ray 5. But please do note that there will be still some differences when you compare them side by side due to different random seeds values that are used in the programs to generate the randomness.

Best regards,
Alexander

Thank you very much for your answer.

This was one of the key features I've been waiting for, great!

Just to clarify that we will be fixing this in the future.
Currently only the "stochastic tiling" randomization mode (if used on its own) will match V-Ray, the other modes require us to send more per-instance/per-polygon data to the GPU.
This is a necessary fix, as something like "By element" will not work satisfactory without it.
Right now all random modes behave like "By render ID", except "By face ID", which uses an internal material/BRDF index.

I normally check "Stochastic tiling" in VRayUVWRandomizer and change the UV rotation º, that's all. This means I will not have different results from v-ray 5 if I continue this workflow, right?

I believe so, yes.

Thanks! Meanwhile, I'm looking forward to the next improvements.
