The material editor in cryengine is brilliant and easy enough to use with a little reading up on the crydev.net forums and cryengine documentation. I wanted to create some dynamic textures in my scene e.g. moving images and illuminated signs, glow for lights etc.
After reading a few things I started work on a test piece for moving textures. I posted the image with the material browser window next to it to show the tiling settings and how it moves. I found that it comes down to the way the textures are laid out so I figured that the use of multi/ sub would be necessary for these types of signs and would need their own texture space I f I wanted them to move without showing other pieces of the static uv sheet!!!!
