This could save a lot of transforms that developers like me add to line things up with a zero rotation.
Also this would save developers from having to change the 3D model then re-import the mesh as this always seems like a guessing game which XYZ rotation matches Unity’s default.
If there was a rotate/translate/scale and re-bake mesh option in Unity it could save a lot of jumping between apps and the RTS data could be stored with the model data in Unity so any changes would flow through and work in the asset pipeline.
