I created a nice rust effect with two textures: rust image and stucci texture with very small NoiseSize (0.004). I used “Nor” button with stucci. It looks great, and does not reflect much light - exactly what I wanted. But… when I’m animating the object, this stucci stuff does not keep still on the object, but changes a little in every frame, making the movie very… restless, you know what I mean?
Oh yes and other question: When using UV mapping, how do you smooth edge between two textures/faces? E.g. if you have another texture for lips it looks weird if the edge between lips and other skin is razor-sharp.
