I have some art assets that are scaled at 1 unit = 1 meter, but when i import them into Unity the scale goes crazy and the model is about 1000x bigger. Any help would be appreciated.
Thanks!
Check the import settings in Unity…
If you’re using Unity 2.1 - Right click your object in the project pane and the hit the Import Settings button (Or hit the “Settings…” button at the top of the pane).
There’s a parameter called Mesh Scale Factor. Change it to import your meshes in a different scale 
In Unity 2.5 it’s in the inspector when you select your mesh, under FBXImporter, and is called Scale Factor.
