Hello, I have a error: "Error, T15428: FindInvalidDataProcess fails on mesh normals: Found zero-length vector", when game converts mesh from FBX to trainzmesh. This error only lod0. I found mesh, where is this error. But, I don't know how fix it. Trainz Wiki hasn't information about this error. I use for export to TRS19 Blender 3.0. Plaese tell me: how fix it? I hope that community help solve fix this error. Thanks.
