TIG: Did as you say, and that solved my problem and also got my slices in a better shape (due to the size of the model). I upgraded the plugin to Slicer5 and Im enjoying it even more Jean: And now I can atlast get rid of these colours ! I'm glad I made an account here, you can't expect any better support than this. Hopefully in the future I can provide the same support as you guys do. Cheers!
