Shrinkwrap/Data Transfer for Multires Data

Currently, multires only supports data transfer between two meshes with identical number of vertices.

Proposal:

A button added to multires modifier that...

• Takes another mesh, with different topology and multires modifier, and transfers it to current mesh's multires data
• Uses something like geometry proximity or raycast to interpolate/approximate data from source multires
• Can be applied in a way that alters both the base mesh (so basically like shrinkwrap) and most importantly copies the multires data as accurately as possible

Use Case

• If base mesh needs dramatic retopology change without having to worry about corrupting multires data
• If I have high-poly voxel remesh and want to transfer it to multires workflow
