cross-hatched looking render?

hi, i was rendering an image i created in the 3d window that looks perfectly normal but when the render window pops up it looks like its been drawn using “cross-hatching” (best way to describe its appearance). any idea what the problem could be?

thanks

Can you post a screenshot?

nevermind actually, i just realized my lamp was out of place, thanks anyway!

No problem. That was a quick resolution :smiley:
