 +If you are just looking for a quick way to get models importing into Unity properly, take a look at the [[https://pontoco.notion.site/Pontoco-FBX-Import-Export-Settings-7b363beb7f7249f2bca6d6bdbcae6c5d|Pontoco Import/Export Settings]].

 +The [[https://github.com/AStrangerGravity/fbx-sanitizer|FBX Sanitizer]] tool can be used to validate an FBX file to verify that it will import into Unity with correct scale and rotation.

-FBX is in cm by default, but can support other units. Other unit scales are achieved in FBX by by setting ''GlobalSettings->Properties70->UnitScaleFactor'' property in the fbx. For example, a 1 meter cube in 'meters' should be stored in an fbx file like:+FBX is in cm by default, but can support other units.

 +++++ Instructions for Maya |
 +Maya uses the same coordinate space as Unity. Just use the default export settings!
 +++++
 +
 +++++ Instructions for 3DS Max |
 +Max uses a Z up coordinate space. 
 +1. Make sure to always have "Z-Up" selected when exporting in the FBX Exporter.
 +2. Check the "Bake Axis Conversions" box in the Unity importer. Unity will correct the coordinate axis.
