I figured out the Math behind how world alignment works by deconstructing and experimenting with the World Aligned Texture node. But that method isn’t correct either, this style of projection is an improper use of tangent space normal mapping. This video supposes that you already know the stuff If you just want to map a single texture (say, triplanar grunge) to all sides, this should be a nice cheap solution. This method works correctly ev -Optional Detail Map channels - blend albedo, roughness, normal, and ao channels with your base textures-Optional World-Space (tri-planar) mapping on each layer (base, mid, top)-Optional UV Channel choice for each layer-Non-Proportionate UV options-Shader is commented on and organized - easier to understand and learn from Cheap triplanar mapping optimized world aligned in unreal Hi everyone!
