It works. I've inverted the map only in transparency. In vray, black means transparent.

? White is transparent...

[stefanq]

Yes, white, apologies. I'll correct my reply.

[stefanq]

It works. I've inverted the map only in transparency. In vray, WHITE means transparent.

Thanks for response !

Yes, white is tranparent. You can see on my transparency settings that the map is inverted. If not, fills would be plain and lines would be transparent.

Stefanq, what are your transparency settings ?

[stefanq]

Hi, I used your settings. Default render settings, only a HDRI image in background.

make sure the alpha channel is selected in your vfb channels options.

I've found the problem.

I've a reflection layer on that material and the refract IOR in the Fresnel editor was set on 1.55. Result with decrease to 0 :

Thanks a lot for your help !

[thomthom]

0 ? Doesn't that effectively void the whole reflection layer? Then you might as well just remove the layer all together.

[andybot]

Yeah, the reflection layer will do that (reflect the environment)
