Stochastic Flake Won't Render Behind Glass

[cg4]

Hi,

 

I've encountered an issue while attempting to use Vray Stochastic Flake. My Scene requires me to render a material with Stochastic Flake behind a pane of glass.

 

However every time I render this the flake does not show and renders black.

 

Hopefully this is something simple that I'm missing when building the material, but any help would be much appreciated.

 

Im using 3DS Max 2017 with Vray 3.40.02

 

I've attached an image to show what I'm getting in the render.

 

Thanks

I've tried it here and it is working as expected .

I'm using Max 2016 and VRay 3.6

a screenshot for the material setup could help to identify the problem or maybe it is just a bug in older versions .

Thanks for your help,

 

I've attached a screenshot showing the breakdown of the flake material and also the glass.

 

Mine is currently a blend material, but I have tried this with just the flake on its own and the result is the same. So I'ts either the flake causing the issue or the version of Vray as you said.

 

Thanks

You don't need your clear coat to be refractive for a start. Change the refraction colour to black and see what happens.

Hi Chris,

 

Thanks but I've resolved the issue.

 

I just had to increase the reflection/refraction override depth value under Vray Global switches and this corrects the problem.

I suspected that depth value would be the problem as for most of glass material problems are =D

I'm glad you resolved it !
