Hello! I’ve spent a few hours searching for methods of overcoming the UV texture warping and labelling challenges described below. Hopefully someone can point me in the right direction. Next day edit, I’ve since stumbled across my own solutions to the issues and have posted them. Thanks very much to everyone who commented potential solutions.
Issue: UV textures warped despite mesh being uniform, and getting a ‘failed to prepare nurbs for tessellation’ message.
Solution: Select the model. Open the ‘Unwrap UV’ function. Select the ‘Set direction guide’ and click two points along the mesh horizontally. Confirm and click ‘Unwrap’. Then you can rotate your texture to the orientation you like and it won’t be warped. Didn’t need to retessellate in the end, so avoided the ‘failed to prepare NURBS’ error message.
Issue: Labelling bleeding through to both sides of model.
Solution: Use the ‘Split Object Surfaces’ function to make the model faces independent. Unlink the materials in the parent that is generated (it will also unlink all the child materials automatically). Turn the label off in the material settings of the face you don’t want it applied to.
