I think the built-in feature for downloading textures in MetaHuman Creator is very poorly designed. Textures should be included when the MetaHuman Creator components are downloaded, rather than requiring unbinding and rebinding every time you switch resolutions, only to download the textures again. Moreover, when downloading textures above 2K in MetaHuman Creator from different countries, there is a 98% chance of a server error. In any case, I have never successfully downloaded a 4K texture even once.
