Rhino VRay to Max VRay workflow

[Morne]

I've tried so many things, but nothing seems very streamlined

3ds truncates the materials, so useless
fbx give y-up, with no option to change during export or import
obj hangs with many objects during import
collada gives multiple materials with same names
etc etc

I've done plenty of projects from Rhino to Max, but it's never streamlined and the same method doesnt always work for each project.

Also, there's a mix of vray materials and rhino materials. I can pack the vray materials, but doesnt look like you can pack the rhino materials
