Help:VE94
From TrainzOnline
This asset requires a shadow mesh, but the mesh table does not contain one.
Certain asset types are expected to be provided with a shadow mesh. If the shadow mesh does not exist then this warning will be emitted. If a shadow is not required for the asset, or if the shadow is provided by in-game functionality, then the warning can be ignored.
Example:
! VE94: This asset requires a shadow mesh, but the mesh table does not contain one.
