 ====== FBX Importing ======
 Importing FBX files in Unity with the correct scale, rotation, and axis is fraught.
+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.

+++++ Instructions for Maya |
+Maya is not able to export in Meters without applying a scale to the object. This is because Maya works in a CM unit internally, even if you set it to display meters. If you want to get a unit transform when importing to Unity, you must model in cm, //pretending// that you're modeling in meters. Then, import into Unity with the 'Convert File Units' checkbox unchecked.
+This has the unfortunate result that these FBX files will import extremely tiny in any other program (like Blender). However, it's the only way we've found to get Maya to export to Unity without a scale.
+++++
+++++ 3DS Max |
+DS Max can export in meters if you set the "System Unit" to Meters. See the [[https://www.notion.so/Pontoco-FBX-Import-Export-Settings-7b363beb7f7249f2bca6d6bdbcae6c5d|Pontoco Import/Export Settings]].

+++++ 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.
+. Make sure to always have "Z-Up" selected when exporting in the FBX Exporter.
+. Check the "Bake Axis Conversions" box in the Unity importer. Unity will correct the coordinate axis.
