Enhancement: "bake from other mesh"
Closed, ArchivedPublic

Description

The attached patch enhances baking by adding a mode to bake from another mesh: then, not the original point on the surface is used for baking, but two rays are shot from that point (outward and inward), and if some other mesh is hit, the hit surface point is used instead.

This is useful to bake things from high to low polygon meshes (which are e.g. common in game development). For example, normal maps, textures (and potentially other material properties) can be baked onto images and used by realtime 3D.

The patch as attached is rather unlikely to be suitable to applied... it's more like a proof of concept how it could be done.
