 \* The children/sub folders will be created automatically based on the blender file location in your folder hierarchy. (E.g. "C:\Users\kye\Documents\Assets\DigiKrafting\Content\Meshes\Logo\Logo.blend" will create "C:\Users\kye\Documents\Unreal Projects\DigiKrafting\Content\Meshes\Logo\Logo.fbx")
 
+# Override Preferences 
+
+Create a text file named blender_addon_ue.json in your source project folder, mesh folder or both for preferences for different model types, the addon will search recursively back to the root folder of your drive for any "blender_addon_ue.json", so don't create it in "c:\blender_addon_ue.json" or "/blender_addon_ue.json".

+\* For a project based setup be sure to set at least "option_ue_src" and "option_ue_dst".
