Blender Normal Fixer // Clear Custom Normals Script

I super simple script that let's you clear the custom normal data that often messes up the normals when importing models from other 3D software.

This script is based on the script found here: https://blender.stackexchange.com/questions/89685/clear-custom-split-normals-data-on-all-objects

The original script returned an error if any empties or curves were selected as well - This has been fixed for this version.

For Blender 2.9/2.8
