Hey there, I have a major problem regarding the usage of rigged 3D-characters out of 3dsmax with Shapeways. Since posing them results in partially self-intersecting meshes, I can't upload the files to the site, as the meshes seem to be regarded as having "inverted normals". Self-intersection occurs for example when the character's arm is held close to its body, so that a part of the arm or the elbow dips into the torso, or usually in "tight" areas, like the armpit. This isn't a problem when rendering, but obviously it isn't accepted by Shapeways. Now, how do I pose characters, without self-intersections? The only solution would be to "boolean" the mesh with itself, thus creating one solid object. Unfortunately, to my knowledge there's no tool in 3dsmax to perform a "self-boolean" like this. Any ideas?
