A handy ultra-fast Blender add-on; by right-clicking on an object, it drops a PBR material setup. It instantly prepares image textures for your base color, roughness, metalness, and normals with the right color spaces and mapping coordinates, and handles Direct X to OpenGL normal map conversions with a single click. Now you can finally import DirectX or Unreal Engine maps without seams or artifacts.
It took me some time to figure out the proper coordinates for all the nodes, the material graph looks clean
Click on a mesh and choose either OpenGL (for Blender or Unity) or DirectX (if you don't want to convert normals inside 2d software but want them to work in Blender anyway)
I also added C- numpy array processing for maximum speed and reliability
All addons are addons that I use in my daily workflow and improve over time when I come up with better ideas
