Hi there I have a few Game Art questions and ideas that I would appreciate any relevant feedback on 
Topic Normal Maps with 2d Sprites
I’ve made a HDRI using Blender to render 2d normal maps for sprites,
and wanted to know is there a way to add the normal maps to the 2d sprites node in Godot?
Here’s a link to the sprite + normal map files

Also I have attached a link to my how to video if you preferred to make your own sprites with normal maps

The files in this is all original and you welcome to use it for commercial or personal use 
Any feedback will be appreciated.
