hello, thanks for providing a simple patch to reproduce this effect.
this artefact came from the default light model in Gem : lights are computed for both side of mesh.The best solution is to remove this option (see attachment).
I usually disable it anyway since it is unneeded if you are careful with normals, and disable it can improve rendering speed. cheers c Le 10/01/2013 16:22, Max a écrit :

Looking for a solution.I think, this is because your viewpoint come too close to your geo (sphere). Put a [max 2] (for example) on your Z axis for the viewpoint to avoid collision.i don't think it's that. i simplified the patch a bit more: with GEM: ver: 0.93.3 GEM: compiled: Nov 10 2011 i have the same phenomenon here. _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
