Interactive Rendering Vray 3.70.01 FP7.1.0

Scene: https://we.tl/t-ek9MaAQlIz

Same issue as https://forum.itoosoft.com/forest-pro-(*)/max-2020-1-and-vray-3-70-01/msg24579/#msg24579

Any ideas?

Hi. Thanks for the scene. Yes we found that 2 sided meterials are not rendered correctly with this vray version in IPR mode. We will check if that can be solved from our end.


Thank You.

I can confirm it's a V-Ray 3.7 bug, because happens also with VRayInstancer.

It happens with FP7, but not with FP6, because we use new rendering methods more similar to VRayInstancer.
That lets us to implement new features, as to inherit materials directly from the source objects, instead to use a multisub material.

You would report it to ChaosGroup, but probably they're not supporting 3.x anymore.
By the way, V-Ray 5 works fine.
