I've created this house in blender. I used Mutiple Materials each with it's own set of textures. Each part of the house has been selected and placed in a UV map with it's texture. this comes to about 10 parts in all. The house looks just the way i want it to. However I need to bake all the textures into one texture map. so I can use it in Second life. But i can't get the texture map, I created a new UV map, I select everything in edit mode. lay out everything with smartproject and pack in the islands. create a new basic image, black (2000x2000) in the UV editor. So now i have my design layed out flat, everything is selected. And i hit Bake. But then everything becomes one texture. If i select a different material and click assign and bake again, everything becomes that texture instead. All i want to do is to bake all the textures and materials at once. The only way I can create a texture map now is to select each part of the house one at a time, Assigning the right material and baking each part of the house one at a time, but even then the baking mess up. if i select the whole house, everything because one texture again. Here's a Imgur picture of the house, all textures applied. the second picture is the failed baking attempt. http://imgur.com/a/oSJXw
