This mesh file is affected by an FBX importer bug and will behave differently in newer asset versions.

This warning may occur when Trainz detects an FBX file that has an embedded coordinate system that is different from Trainz (Z up, Y forward). In older versions of the FBX importer, the embedded coordinate system was ignored, which could result in some meshes having an incorrect rotation or scale when imported into the game. Some content may rely on this, so backwards compatibility is maintained for the old import behaviour.

For assets with trainz-build 5.7 and later, the FBX importer will now respect the file's embedded coordinate system, and rotate/scale the mesh to match the coordinate system used by Trainz.
