Hello all, i'm quite new to Archicad and I was wondering which setting do I have to use so I can render my image without background. I can't make it happen, cause if I remove background, image goes very dark. I just want my render without background so I can add it in Photos...

hey, i'm kinda new to Archicad and 'im having problems with my walls. How can I set them to follow my mesh? Here's a pic to ilustrate. thx http://i66.tinypic.com/1t9f91.png
