Confusion about input

If I got this right, If I need a color mesh for lets say my own rgb image, I first need to convert it to a 3d mesh using some other available models such as PiFuHD or EVA3D etc and then input that mesh into this using the retexturing weights? Is this correct, or am I missing something.

Start by reviewing the repository's documented input requirements and the retexturing weights referenced in the issue. Clarify whether an RGB image must first be converted to a 3D mesh with another model, and document the expected workflow and inputs. Done means a newcomer can tell what to provide without relying on external assumptions.
