I mean this in 2 ways:
- The model thumbnail shows a mirror image of the model, left is right and right is left.
- Also, the direction the models are facing for thumbnails in AssetForge is 180 rotated from the direction the models have to face in Unity for GetAssetPreview.
p.S. The tool I use for modelling lines up with Unity as well. I was just rotating my models 180 degrees for AssetForge. I hope this gets fixed!
