Setting random materials

[piac (Giulio Piacentino)]

Hi @Bara_Sabsabi

(I split this lonely comment to a long-closed topic into a new one, so that it would attract more possibility of help.)

All you need to do here, is to understand what Material Index your Vray materials have. Then, select from those indices and set the values as explained here:

Python: How to assign attributes to existing objects?

Here is how you’d do this using rhinoscriptsyntax: import rhinoscriptsyntax as rs obj = rs.GetObject("Select object") if obj: index = rs.ObjectMaterialIndex(obj) if index == -1: index = rs.AddMaterialToObject(obj) rs.MaterialColor(index, (127, 255, 191))
