Blender 2.74: More Features

.blend Files & Libraries

  • You can now enforce generation (and hence saving) of previews for materials, textures, lamps, world and images datablocks (File → Data Previews → Refresh DataBlock Previews menu entry), useful for material lib files e.g. Note it can take a bit of time when using Cycles materials - and do not forget to save the file once done!
