All the textures and opacities should have different names, otherwise, they will work as one, creating conflicts among themselves.
Save your textures in .jpg , with an 8 / 9 quality
Use the wireframe maps as reference
For the shadows, put the textures provided here in "multiply mode" in a new layer
Thanks for support
