Latest pull and build of the Alchemy Dire branch has some serious issues with texture mapping on mesh.
I'm not certain what is the trigger that causes this but only certain mesh objects display this issue, most namely my house at http://maps.secondlife.com/secondlife/Raiden/183/47/28 my kitchen in the same area, and my favorite pair of boots.
When this bug manifests all "texture faces" of the mesh will be using the same texture/tint/alignemtn data. It's as if the mesh is being treated as a mesh with only a single texture face. Sometimes if I select face the afflicted face in the editor window it will cause the proper texture to load but that only sometimes works.
