Vertex Forge is a flexible editor and runtime tool for baking any kind of textures and maps directly into mesh - per vertex. Those can be regular texture assets, camera reflection or ambient lighting cubemaps, and even scene lightmaps.
Editor tools allows baking simultaneously 12 textures inside any mesh vertex buffers (vertex color, uv0 - uv7, normal, tangent) and inside any channels of them (R, G, B, A).
Run-time API extends Unity’s mesh class by adding texture baking methods to it.
