Unity Guide

Simple Export ships with an FBX preset for Unity. Select the correct preset in Properties -> Output -> Simple Export -> Preset. The preset ensures that the following settings are configured correctly.

Export to Unity

Exporting static assets to Unity is straightforward and only requires 3 simple steps:

Step 1: Select the Unity Preset

Make sure the Unity-default preset is selected

Step 2: Create an Export Collection

Create an export collection - that will now automatically apply the settings for Unity. This can be done by using the plus button in the Export List, right-clicking on the collection in the Outliner or right-clicking on the parent object in the 3D Viewport

Step 3: Move the Collection to the Origin

Select Move by Collection Center in the Pre Export Defaults to move the collection to the origin based on the collection offset. This is important for Unity, as it expects the pivot point of the mesh to be at the origin.

Step 4: Export the Collection

Export the collection from the Export List, the Outliner or by exporting all selected collections.

Import to Unity

You can now simply import your asset into Unity by dragging and dropping the exported FBX file into the Unity or using the import asset. One thing to consider to clean up the transformations is to Bake Axis Conversion in the import settings. This will ensure that the mesh is imported with the correct transformations and orientation. This will ensure that there are no weird rotaitons on the asset.

The Simple Unity Export Preset

Setting	Value	Notes
Path Mode	`Strip Path`	Removes texture path since UE handles it
Scale	`1.0`	Blender and UE share the same scale
Apply Scaling	`FBX Unit Scale`	Ensures correct transformations
Forward Axis	`- Y Forward`	Matches Unreal’s coordinate system
Up Axis	`Z Up`	Ensures proper world orientation
Apply Unit	✅ `Enabled`	Ensures proper world orientation
Use Space Transform	❌ `Disabled`	Helps maintain consistent transforms
Apply Transform	❌ `Disabled`	Avoids hierarchy issues with animations
Smoothing	`Face`	Edge smoothing can cause shading issues
Apply Modifiers	✅ `Enabled`	Ensures the final mesh is exported
Tangent Space	✅ `Enabled`	Required for correct normal maps in UE
Triangulate Faces	✅ `Enabled` ?????	Triangulate caused issues in the past, because Blender would not maintain the custom normals
Add Leaf Bones	❌ `Disabled`	Unreal doesn’t need extra bones
Animation Export	❌ `Disabled`	Only exporting static meshes
