H! I was having problem on my rendering, since I only have a few experience in using photoshop. I want to remove the background inside my rendered picture. but how? I tried the background eraser tool, but it said that: "Could not use the background eraser tool because the target channels do not cover the composite: any ideas? Thanks! EDIT: I SOLVE MY PROBLEM AFTER A FEW HOURS. CLOSED
filter>extract highlight the edge then use the bucket tool, click preview and see if your happy or does it not work for you?
