Hi Marcus, Thanks for the reply. I am using python maya api 1.0 . The problem is that I am not able to anything because scene crashes so it's hard to test through connections. I will try using attributeAffects. I am trying to effect the mesh based on intersection by using closestIntersection , so there is no secondary output. Is it a good way to operate on the source mesh?
