Thank you valerostudio but I have done this step by step as you have written and it does not solve my problem yet 😞 When I apply saved material from VRay material library, texture is in scale, but renders flat. When I add vrmat with the same diffuse but with other layers and parameters texture is rescaled again (25,40cm x 25,40cm not 80cm x 80cm). The other way around is the same (first load vrmatt, then apply material from paint bucket). Tested in macosx and in windows.
"This is only available in 2.0, 1.49 did not save the material settings with the SKM file" I have 2.0 so that is not an issue.
Once again, I have vrmat (with all layers and parameters) and skm (textured properly) files. I open a new scene, want to load them both to work properly, not to make additional moves in SU. Especially when we make a new scene on different SU on different machine.
