Custom Map Makers

Hey guys, I just found on another forum a trick for making a 16 frames animap image.
Has anyone ever tried this?

Nice, i was trying to to this a long time ago.
I tried to use textures with animap shaders as part of another shadermap shader.
I don't think it worked out well. can't really recall lol.

I can't see why it should not work, tought shaders are not my stringes area.
