I would like to be able to create a texture atlas from the rendered frames of an animation. In my case, the animation will be 6 images that are 1024x1024 pixels, and I would like to make a 3x2 atlas of them, so a single 3072x2048 image. Doing this manually one time would be fine, but I need to do it 32 times.
Maybe this is possible with the compositor? Not really sure.
