Well the only way to make a material is with procedurals in the DTE. I'd like to be able to load my own pictures into the DTE to use as well but haven't figured out how, instead I'm stuck with the preset bumps, etc. If anyone knows how to do this please let us know.IOW how do you add a picture to the texture library in the DTE (not the material library next to the edit menu). It seems to only accept .brt files. Also whenever I'm in the texture library and select user the window disappears and I'm back to the material editor but nothing works, everything I click on just beeps and I have to shut Bryce down to get out of it.
