Oh, that reminds me. There's another problem with Truform.
In order to "fix" the problems of Truform, it is certainly required to make the normals of at least some of the vertices of adjacent triangles different. Since doing this adjusts lighting calculations, this will lead to discontinuities in lighting. For this reason, I have a hard time believing that "auto-Truform" would always produce a good image, even if it might resemble the low-detail geometry accurately.
This also begs the question of vertex caching. Unless ATI also has a plugin for automatically optimizing Truform-optimized meshes, then those meshes optimized for Truform could be quite a bit less efficient. As a point of interest, has anybody checked to see whether running this "auto-Truform" plugin increased file size for the mesh?
