I have been trying to import a series of head scans into blender without luck. Each model I import appears as an entry in the scene listing but does not appear graphically in the 3D viewer. The files I am trying to import are PLY files and STL files. I can view the files in MeshLab, Matlab and Mathematica, which is where they were created/processed. I am guessing the problem is that the files have errors of some kind and this prevents them from showing up - any ideas how to troubleshoot this?
I am using Blender 2.62 on Mac OS 10.6.8. I tried attaching the files but received errors, they are probably too large (2+MB)
