======================================= Alpha blending + sorting was revised, to fix bugs and get it to work more predictable. * A new per texture face "Sort" setting defines if the face is alpha sorted or not, instead of abusing the "ZTransp" setting as it did before. * Existing files are converted to hopefully match the old behavior as much as possible with a version patch. * On new meshes the Sort flag is disabled by the default, to avoid unexpected and hard to find slowdowns. * Alpha sorting for faces was incredibly slow. Sorting faces in a mesh with 600 faces lowered the framerate from 200 to 70 fps in my test.. the sorting there case goes about 15x faster now, but it is still advised to use Clip Alpha if possible instead of regular Alpha. * There still various limitations in the alpha sorting code, I've added some comments to the code about this. Some docs at the bottom of the page: http://www.blender.org/development/current-projects/changes-since-246/realtime-glsl-materials/ Merged some fixes from the apricot branch, most important change is that tangents are now exactly the same as the rest of Blender, instead of being computed in the game engine with a different algorithm. Also, the subversion was bumped to 1.
