normal mapping problem

hello people,

i tried textureing an object with two textures , one as a texture and mapping and the other for mapping only and it looked good but when i changed the view i found weird shapes on the texture

what are these??? and how can i remove them?

For the third texture (name Tex) change the mapping coordinates from Generated to UV

it’s still there but the shapes just changed also it changes the look totally

i just want the look as it is but without these polygons
