Export settings from Blender 3D to Unreal Engine 4
Export settings from Blender 3D to Unreal engine 4 is common question and there are several things good to remember to get this work correctly. Check my few tips below and also image sequence with detailed descriptions to make sure you have good export settings.
- Scale – Blender 3D and Unreal Engine 4 work in different units. In Blender 3D change scale when exporting to 100, or in Scene Tab, change Units to centimetres, and when exporting Scale remains at 1.
- Apply Rot / Loc / Scale – always rotate, location and scale before exporting.
- Smoothing and Tangent Spaces: Both programs use it, so you can process them in Blender 3D or generate them in Unreal Engine 4.
Option 1. Generated Smoothing and TSpaces in Blender:
In exporting settings in Geometry Tab set Smoothing to >> Face and select Tangent Spaces. Important method for this object must be Ngons free and have clean uv’s. When importing in Unreal Engine 4, select Normal Import Method to >> Import Normals and Tangents.
Option 2. Generate Smoothing and Tangent Spaces in Unreal Engine 4:
In exporting settings in Blender 3D in Geometry Tab, set only Smoothing to >> Edge. When importing in Unreal Engine 4 set Normal Import Method to >> Compute Normals, and Normal Generation Method to >> Mikk TSpace.
For static mesh: select the object before go to export.
For skeletal mesh w/o animations: select the armature first, then object and go to export.
