Hi guys, I'm working in a project and I'm using mtl_specBump from the default shader library for my block walls but after I compile the game I'm getting some weird effects. Basically, if I'm standing in facing one direction the shader displays well but then if I turn a few degrees to the left or the right is like if the shader disappear, or sometimes the wall shows white. I have no clue what could be happening. Please take a look at the picture below to see what I'm referring to. Any help/advice is more than welcome:
