One other feature is that you can change the orientation by selecting uv-vu in the menu, and change the height and with size of multiple props to have a similar texture effect, very useful then creating a prop like a room by primitives and want similar textures on all parts. The biggest problem with the material room is then I want to tile a texture for clothes I often has to use a very small number like 0.1-0.005 and its very hard to preview.
