I have a single nurbs surface which uses a custom mapping object (mesh). The RenderMesh of the surface was extracted and unwrapped in another sofware, then re-imported into Rhino so i can use it to have better UV-Mapping.
If i assign a texture to my surface, it looks extremely blurry (in RH5 and RH6). The same texture assigned to the mesh looks very crisp. I’ve found that the reason for the blur is the “Advanced Texture Preview” option in the Rendered Displaymode. If i turn this OFF in RH5, the texture looks crisp on the surface and identical as when applied to the mesh.
If i turn OFF “Advanced Texture Preview” in RH6 it also removes the blur, but the custom mapping link is lost and cannot be restored by using the
_ApplyCustomMapping command again. Somehow, i can only return to that custom mapping state if i use the
_UVEditor command once. (I just make the rectangle and click OK and all is well).
Is there a reason why “Advanced Texture Preview” is ON by default ?
Can i turn it OFF via a command or code ?
