Just finished a modular M4 build with swappable attachments, made entirely in Blender. - Workflow: reference + blockout -> high poly -> retopo -> UV (UDIM) -> bake -> Substance Painter -> Marmoset presentation - 44 separate parts so every attachment works on its own - LOD0 280k tris down to LOD3 34k tris - 4K/2K/1K PBR UDIM textures, 20 skins from a single material setup. Images: final render, wireframe/LOD comparison, UV layout. Happy to answer questions about the retopo or UDIM setup.   submitted by   /u/Efficient_King6770 [link]   [comments]
