blocky / triangulated: Select your object, open the tools panel (hit t) and under shading, click ‘smooth’ Also in the modifiers (Wrench icon) add a subsurf modifier
The pixels (I am guessing are due to low samples in cycles) By default the max samples is 10, which is never under enough. Under render settings (the camera) go down to samples. Increase preview and render. Try 100, 300, 1000. Every scene is different. If you set preview samples to 0 it will render indefinitely.
Well I Tried that, but it didnt work. here is a picture on how it does look http://tinypic.com/view.php?pic=wco005&s=8#.U_SwQ4ERvRY
it dosent make sense for me why on earth the material thing would be so Flashy when i took the entire model and painted it on.
Weird patterns like this are in most cases a sign of overlapping geometry: Two objects occupying exactly the same space so that the renderer gets confused which one is supposed to be on top (aka “Z-fighting”).
Look out for doubled geometry, redundant mirror modifiers, etc.
And btw, if you had posted that image at the start of this thread, you had saved us the guesswork and would have gotten your answer faster.
