White layer and wrong animation problem

Some problems with animation and material. I have made model in Blender But when I import this model in Lumberyard and assign material, it seems the editor adds an additional white texture or something. I tried different options in material editor, but no result. Here the video how it looks and works in Blender, and then in Lamberyard. Any ways to remove this white layer? https://youtu.be/6qwxXj8Aqqo

There are also an animation problem, I tried different expot FBX settings and Lumbermixalot plugin also, but animation still works wrong. The most strange thing is that knight also was edited in Blender(its from Mixamo) and his animations works perfectly well (I have exported his animations with the same settings).
