The main idea of solution is to create second UV set where UV islands' borders are the hard edges of the mesh (via Unfold). Then we export the mesh to two OBJs with different UV sets. In max - first we process the mesh with unfolded UVs - via TexTools' "Smoothing Groups from UV" algorithm (i've ripped a part of it into…
Rather strange trouble occurs every time I export my geometry from SI 2011 to Max 2009. The issue can be described by the following pictures. 1) Say, I create a half of a sphere and unwrap it. 2) Create a COPY (not CLONE!) of it and mirror the geometry via negitive scale along X axis. 3) Fix the right half's UVs by…
