Phew, well, guess we could use render mode for transparency issues and normal 3D viewing mode for most other models, for the time being at least. BTW, I see that I can set palette transparencies on my end with the .PNG files just like a .GIF. Luminaire, would it help any if I set all RGB = 0,0,0 colors to be totally transparent? Given what halkun said earlier, I'm not sure if it would make a difference.
tushantin, if you have a PC capable of handling Blender, you're already ahead of the game as far as I'm concerned. Even if you can just load up models with Luminaire's script and take screencaps, it's better than I can do right now -- I think my ATI Express graphics card chokes on the program, and when I fiddle with the graphics card settings, my PC tends to crash randomly.
