Hello I am trying to refine a Mesh that I already have using the refinement stage of Magic3D. I am getting dimension errors. Could you please help me?

Hi! I believe ShapeLoss is only suited for constraining a density field to a guide mesh, while the refinement stage of Magic3D has an SDF representation. To refine a guide mesh, you could
(1) first use Fantasia3D to refine the geometry (currently only support sphere and ellipsoid initialization, but I'll push an update to support initialization from a given mesh tomorrow)
(2) keep the mesh fixed and texture it using SDS/VSD (will support this texturing feature in a few days)
