by the way, how can I import my whole model into Unreal Engine?)
File => import into level
Try disabling ‘create collision’ in the import dialogue. From the callstack it looks like the attempt to generate a convex collision mesh is hitting the max data write size.
It’s still unlikely that you’ll be able to have a single uasset that large. The uasset for a Nanite enabled mesh has to contain the original mesh, the lossily compressed Nanite mesh, and the low-poly nanite fallback mesh (the original mesh gets thrown out when packaging a build), and that combination is still likely to hit the 2GB write limit.
