V-Ray MtlVRmat doesn't work.

Hi all,

I try to assign .vrmat materials to the vray shaderball, but when I start the render the object disappears.
I imported .vramt materials from .vrscene files and downloaded .vrmat files from the internet, but none of the materials worked.

Do I have to activate something in order to render .vrmat materials, or do I have to combine the V-Ray VRmat - Node with another node to work ?

Thank’s.

Seems to work at my end.
Are you sure “Material Name” parameter is set correctly ?
What are your Houdini, V-Ray and OS ?
Here an explanation how to set Material Name parameter: Which material tree to use. Top-level <Asset> name or MtlSingleBRDF name if .vrscene
