Hi Probably a really thick question but somtimes im finding that the materials im using that are pre-installed with VRay appera on my model (not when rendering) as a repeated vray logo. Why is this happening? Thanks ---

Why is this happening? > > Thanks Hi Southsea2016, The ‘logo texture’ is displayed when there is no bitmap texture in the shader and all the maps applied are procedural. The reason for the ‘logo texture’ is to let you change SketchUp material size in case the procedural map uses 2D placement. 3D maps (like Noise) will not be affected by the SketchUp material size.
