I greatly appreciate your paper. I would like to ask if your BRDF decomposition mentioned in Fig18 can be directly applied to the Unreal Engine or Unity Engine?
The BRDF properties are pixel-wise defined on the vertex. You may also use UV mapping tools to extract a 2D UV map from the mesh and extract texture/roughness/metalness maps.
