Hi @Gorbatovsky It would be cool if we could add such a Workflow to 3D-Coat. It is often very necessary. For example, you make a model for the client, draw different masks... And then the client changes the model wireframe and UV... And makes a model with UDIM, not one channel... Just this method in MARI helps to solve the problem of transferring all the masks and textures to the new model - https://texturing.xyz/pages/transferring-single-uv-to-udim Please add this to 3D-Coat =)
