I have a huge problem. I’m a game developer and currently trying to create a level with Lego buildings. So I export them as zmbx from mecabricks and import them to blender, combine the meshes (joined them into one) and then export it as fbx which I than can import into ue5. The problem is that the mesh has to many materials and nanite can’t handle a mesh with over 64 material slots (mine, a simple building, has around 650), each brick has a material, which is totally unnecessary cause the most of these materials have the same color/texture. They are called like „mb:o:234:199“, when the last number is the same (199) all these materials have the same color/texture.
And then for example other materials with the ending 134 are also the same … I saw that a lot of guys found a way to combine all materials into one. I tried some blender addons like creating an atlas, but for that you have to create a new uv map which my pc can’t handle because of the mesh (Rtx 3070ti ox, ryzen 7 5800x, 32gb Ram). And then I get a weird texture and the mesh is completely filled with random colors. I’m new to blender so I have no other ideas. Please help
