I want to use a Specify preview mesh feature in the ply2vrmesh.
and preview mesh of the existing vrmesh is also replaced.
Since V-Ray 3 SketchUp/Rhiono does not have a vrmesh output option now, it is required.
Hello,
The next feature update for V-Ray 3 for SketchUp and Rhino will feature enhanced vrmesh creation options, including preview mesh.
Kind regards,
Peter Chaushev
Thanks for adding feature. 
In addition it is useful to have the function of ply2vrmeh also.
Can not use “Specify preview mesh” with V-Ray 3.6 SketchUp?
What we are looking for is “to create a completely customized preview icon for Proxy”. It is not reduction.
