That sounds familiar, this project uses a procedural cell based texture also. I will experiment with the texture to see if this resolves things. There is also a mention in the Manual under 'Under-sampling' and I quote...... "Interpolate
Activates interpolation of pixel groups where the threshold is not exceeded. If the option is inactive, undersampling generates mosaic like effects (for example, you may try sampling threshold 100 with no interpolation). " Would this be anything to do with anything ? I am sending the file to Vesa in the meantime.
