My screen size is 1024 x 768 and render window is 850 x whatever......I get my scene all set upand want to render at 1024 x 768 or bigger....I go into render settings and render size to 1024 x 768 when it is finished it is not the same as the preview the top and bottom and sometimes the sides are cut off....How do I get it to render to the exact dims, like I said it cuts the top and bottom off and sometimes loose a characters head or feet.......thanks.
