I’ve never used xNormal myself, but I would recommend something like Substance Painter as it’s now an industry standard texturing tool. It’ll bake out just about any type of map you want including normals, height, roughness, occlusion, emission,opacity, etc. It’s like Photoshop for texturing 3d models. From what I’ve heard xNormal is a bit slower to bake and their UI isn’t all that user friendly. I don’t know of any other similar programs that do what xNormal does. Only other similar tools I’ve used take info from a texture and output the maps like Crazy Bump.
