Unreal Engine Splines Importing From Blender

Blender Curves To Unreal Engine 4  Plugin. Helps export your blender Bezier splines as Unreal Engine 4 USplineComponents.

How to Export Curves From Blender

  1.  Download and Install the Blender 3D addon in blender 2.8 and up. Blender Curve Exporter v1.0.zip . Tested on Blender 2.8, 2.83 and 2.90.
    • There will be a side panel labeled “Curve Exporter” in blender after installation.
  2.  Select all the curves you want to export from Blender and hit the “Export Selected Curves” Button.
    • The file will be saved as “Blender Curves.bcv” on the desktop. You can change filename and save directory in the side panel.

How to Import Curves As Splines Into Unreal Engine 4

  1. Download and Install the Blender Curves Importer.zip  of whichever version of Unreal Engine you prefer.
    • Depending on your purchase, you will either have the Binary Only or Full Source version. The installation and usage is the same:
      • Extract the ZIP. And put the folder in the Engine’s ‘…Plugins/Marketplace’ folder. (you can use any folder after Plugins/ . Marketplace is just recommended for organization.) * This is mainly for the Binary Version. The Source Version can be installed in the  Game’s or Project’s Plugins folder if you wish to modify the plugin’s source code. But it will work just fine in the Engine’s Plugins folder too.
  2. With the plugin installed and enabled, Right click on the content folder and import the “Blender Curves.bcv” file created by blender earlier.
    • The splines will be saved in a folder called “SplineImports
  3. Special usage notes:
    • Make sure you don’t use illegal characters like “? <> . ” etc when naming your curves in blender. These will be read by Unreal Engine and saved as Splines.

If you’re trying to import into Unreal engine and nothing happens after selecting .bcv file then these are the likely causes/scenarios:

  • You did not export “bezier curves” from blender. There are different types of ‘curves’ in blender but this plugin only supports “bezier curves”. Solution: Convert your curves to “bezier curves” in blender before exporting. Blender supports this type of conversion for all curves.
  • Initial Release
  • Export one or multiple curves from blender at the same time
  • Import into Unreal Engine 4 as USubsplineComponent Actor Blueprints
  • Supports editing of blueprints after import
  • Support for 4.27 and 5.0
