comment HLSL: Using instance float input to select texture index, possible?
A good read but these techniques are not available in DX9, and therefore XNA/XBOX.

Well, I am using instancing, which is the problem. +1 for pointing out that mipmapping is possible with texture atlases. I may go that route.

comment HLSL: Using instance float input to select texture index, possible?
What I am trying to accomplish exactly is: I have several hundred instances, and am CPU bound. Draw calls are very expensive on the XBOX360, so I am trying to reduce the number of draw calls that I need to make.

comment HLSL: Using instance float input to select texture index, possible?
I never said anything about only 3 textures. The reason that I don't want to pack multiple textures into a single texture is because then I won't have the ability to use mipmapping, I believe. I don't think that 3D textures are available on the Xbox360 (which uses DX9 plus a few DX10 features). Sticking with your example of 3 textures, how else would I render 3 textures on each instance primitive? A separate pass per texture?

comment 2D shader to draw representation of rotating sphere
I do find that interesting and +1 for the interesting link. However that article mentions nothing about how the mapping of the texture to the circle is done :/
