I've just got my latest Tech Art creation approved on Creative Crash:
Nightshade Materializer is a Maya tool for managing and working with scene materials. It's a Swiss Army Knife -styled tool with loads of features aimed to make the life easier for the 3D Artist and/or Level Designer working in Maya. It's written entirely in Python using the PyMEL module.
