importing an .fbx file from Blender → Unity crashes and shows the following error message: “Error from blender Meshes may not have more than 65536 vertices or triangles at the moment. Meshes ‘Shape_Sphere’ will be split into 8 parts: ‘Shape_Sphre_MeshPart0’, ‘Shape_Sphre_MeshPart01’, ‘Shape_Sphre_MeshPart2’,‘Shape_Sphre_MeshPart3’,‘Shape_Sphre_MeshPart4’,‘Shape_Sphre_MeshPart5’,‘Shape_Sphre_MeshPart6’,‘Shape_Sphre_MeshPart7’.”
Does anyone have an idea or a hint what I can do to solve the problem? Thanks alot.
You need to break up your mesh into multiple submeshes and according to the answers below it’s actually 65,534.

This is a unity limitation. Unity uses 16bit indices for geometry, so you get around 65535 vertices per object max.
However, in my experience importer usually can manually split the model into pieces.
