I've been working on my own multipurpose CGFX shader for Maya for a while now. Figure I'd let the PC community give it a go. I created this shader using Mental Mill and a bit of notepad editing for UI tweaks. The purpose of this shader is to produce a "game like" look in Maya's viewport.
I haven't been arsed to write any documentation for this yet, so just ask away. Please let me know if you find any bugs or have any suggestions for improvements.You can get the shader here (bottom of page).Video Tutorial on how to use it here.
