I have an animation of a lizard coming out of a sewer hole where the lizard layer is in 3D space and actually comes through the hole of a 3D ground layer.
I want to be able to export the ground layer as well as the lizard layer in separate elements so that if I want to make changes to the hue of either I can easily do that with an editing program without re-rendering the entire scene.
The problem is that I cannot seem to turn the ground layer into an effective matte (determining where the bottom of the lizard would be blocked by the ground layer) without losing its 3D capability.
My gut instinct was to find a way to color overlay the ground layer in the scene so that in the editor I could just to a color key to get rid of it. But of course even the first step of making it a solid color (rather than the textured image that it is) means losing its 3D ability.
I hope I've made my issue clear enough. Annnny suggestions would be supremely appreciated.
