CGSphere.com on lunch today. It's a bit like a 3D-chopper's version of PSC. But instead of a daily source they provide a 3D starting point of scene involving a sphere on a grid backdrop.
Rough summary of their rules:
1. You must download and use the scene provided for you.
2. Do not modify the grid plane, as it is required for consistency.
3.You may use any kind of materials and/or textures supported by your 3D program or renderer.
4. You may not, under any circumstances, move, modify, adjust, or relocate the camera.
5. You may use any kind of lighting techniques and features supported by your 3D program or renderer.
6. You may use any kind of renderer supported by your 3D program.
7. You may apply any kind of post-rendering effects such as color correction, glares, highlights, etc, using any kind of digital editing program.
The
gallery has got some great pieces in it.
Might be cool to have a cross-site promotion going between our two communities.
