Well the damage is only done in the jpg saved version ;). I never save original texures in jpg format. The use of jpg is a compromise to get smaller files. I will try a different file format and see if it has to do with the jpg as I'm still not convinced about that as I have used HQ jpgs for long without any problems. ;) Also the fact that it don't smear when it's in contact with the flattened sphere point's more to the fact that the sphere might use another alias algoritm that also effect the texture it's inside it than a jpg problem in witch case I would expect the same problems inside the sphere. Some easy Tests will answer this. Thanks for explaining about the antialias. What helped most was that I realised that the setting for the different tabs in the material was connected to the later alias. I thought it was an separate setting having to do with how scaling of a texture should be handled. This together with the recommendations for most 3D apps to not smooth any textures in advance but in stead leave that to the anti alias process made me do a wrong choise on the settings.
