I’ve only done this with blender, but, when you import the mesh the fbx importer should recognise that you need to assign a skeleton in the importer window, there you select the metahuman base skeleton and then click import. Now you have the new mesh just go to the blueprint of your metahuman and on the relevant section, I.e. legs, change the skeletal mesh and underneath the material for it and that should all be working. You may need to also re-assign the rig within the skeletal mesh as well. Let me know if that helps. If when you import the fbx and it doesn’t give you the option to select a skeleton then you’ve done something wrong when exporting it from maya.
