aiStandardVolume missing from the shader list

[XtaaZ]

Hi,

I noticed that the aiStandardVolume shader isn't in the shader list when trying to assign a new one.
Screenshot attached, version of MtoA: 3.1.1

Thanks a lot!

Assign New Materials shows only the surface shaders for a renderer plugin. Or do you see volume shaders for Redshift?

You'll have to assign a surface shader, and then in the shading group AE, assign the volume shader.
