I am using sketchup 2017 and the materials in sketchup work fine in the model but there are no materials files in the folder in my C drive. The problem shows when I use Vray for sketchup to render my model but if I tried to use sketchup material(in the Vray material setting), it shows "the file can not be found at the specific location".
I am wondering why the materials could show in the sketchup model and it works normal but actually there are no materials files in the SU folder??
I searched online and it says SU 2017 Pro should put materials in the following folder in the C Drive:
C:\Users\TJiang\AppData\Roaming\SketchUp\SketchUp 2017\SketchUp\Materials
But there are nothing in it, I have no idea how the materials could be still used in SU model?
That folder would be for your custom materials. The materials included with SketchUp are in a different directory. They should not be in the User directory.
