(Fixed) Reflection/Refractions Masks not working

V-Ray V-Ray for Houdini Issues
1

It seems reflection/refraction masks are not working as expected.

Reflection/refractions basically disappear when there is anything other than * in the mask field (even if you put a space behind the star).

I hope this can be easily fixed as this is extremely high priority for us.

We are getting some funky warnings in the console as well like this:

sphere_chrome void __cdecl OP_Parameters::evalStringT(class UT_String &,const class UT_StringRef &,int,double,int) const: Invalid parameter name “”

Could u send me a scene showing the issue and the warning?

Sure can do…this is not scenespecific, it happens always.

when I hit render in the attached scene, the right sphere should not reflect the grid but the left sphere and the light. Instead it renders black here.(because it has a fully reflective material).

Tnx, I’ll fix this; you could add “Object Properties” to the “sphere_chrome” as a workaround.
