Unity Editor Tool
Object Baker is a Unity editor tool designed to reduce draw calls by combining collections of objects with simple colored materials into a single object with one submesh, one material, and one minimal resolution texture.
The tool works by combining submeshes into a single mesh, generating a texture from all their material colors, and mapping the UVs of the new mesh to this texture. The result is an identical looking combined version of the original subobjects, decreasing the number of draw calls, batches, and resource swaps required for rendering.
