Dont know exacly where to post this. I am making animations and I have observed that textures with high normal values work in a very strange way. They seem to shiver!! Well, the thing is that it seems that anytime you render a frame the noise value in textures change making a different texture pattern. Is that way? This can be just part of the answer because the same thing happens with normals with image textures.
How can I avoid this???
