Controlling Point Cloud Per-Point Radius with Vertex Color Map?

[Zirnworks]

I can reference PLY files (with vertex colors embedded) into Max with the Ply2Vrmesh converter utility. I have used the vertex color channel to drive the opacity, luminosity, and other aspects of my clouds. However, it would really cool if I could somehow apply the vertex color channel to the rendered radius of the point, as well. All the points are currently the same size. I suspect is not possible within the material since point radius is established in the utility, but is there a workaround somehow? Is there a command I could put into Ply2VRmesh to change -pointwidthmultiplier based on one of the RGB channels, perhaps?
Maybe something in the material editor, itself?

Hi,

the ply format is designed only for polygons and there is no point size channel. The tool supports other file formats that a capable of storing points like alembic and prt. I recommend to use them. They have a specialized point size channel which can be converted to *.vrmesh files.

Best,
