Author Topic: Discrepancy on Renders on Maya V-ray  (Read 322 times)

Hi,

I have been having problem with my Substance Render not matching with Maya Vray Render. I thought it was just between render engine (i.e. production vs game engine).

But when I tried using the Substance Sample Scene, it still didn't quite line-up with my expectation and actually it lost several details. You can see an illustration of the problem here:

You can also see an illustration file here:

I followed the demonstration in this page: https://support.allegorithmic.com/documentation/display/integrations/Vray+for+Maya

And also Wes's demonstration in this video (Substance Painter External Rendering Workflows)
https://www.youtube.com/watch?v=beCoMJ3k9x0&t=1286s

Correct me if I'm wrong but seeing Wes' result, it also didn't line up with the Substance viewport.

So my question is, is this really a somewhat normal difference in renders between game engine and vray? Or are there any settings I should be aware of?

Thank you for looking at the problem.

Hi,

I checked the sample sphere scene from Painter in Vray. I feel like I am getting a pretty close result. There will be differences due to the raytracing from Vray vs the realtime shader in Painter. However, it should be close.

Here is a maya archived scene of what I am getting.

I tweaked the GGX Tail Falloff in the Vray material to get it a little closer. I set the value to 1.5 down from the 2.0 default.

Cheers,
