(adsbygoogle = window.adsbygoogle || []).push({}); Have you ever opened a picture and saw that the background was an un-wanted white? This is how to make that disappear and make it transparent and ready to use for a render:plank:

Nah your trying to get it exactly on the render not a bit around him, I'll post a pic after I do a basic one or if you want I'll make a "Rendering with the Pentool tut" later?
