Discrepancy on Renders on Maya V-ray

[bentraje@gmail.com]

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)

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,
Wes
