Help:VE160
From TrainzOnline
No 'mesh' keys found in .lm.txt file: meshfilename
The .lm mesh file is a plain text file that is used to provide LOD information for the meshes used in the asset. The error indicates that the mesh references required in the .lm file were not found: that is, the .lm file is faulty.
For example:
- VE160: No 'mesh' keys found in .lm.txt file: body/br101_body.lm.txt
The .lm file 'body/br101_body.lm.txt' should be repaired to include the required mesh references. See here for the required file format.
