3D Blender Green Screen

[Noajol]

1. It's Node not Noid editor.

2. Your blue screen was fine, the blue bleeding is called spill, and it happens even with blue or green screens.

3. A difference key is meant to compare a background with and with out the subject. The difference between the two creates the mask.

4. What you were attempting to create is a color difference key. Those are better built by separating the green or blue channel and subtracting it from the other two channels. to make your mask. you get more control.

Thanks, I'll give this a try. By the way you can fix the blue edge on the bird by using the dilate/erode node.

hi, im wondering if you could send me a finished project, im using blender 249 and i cant seem to get it quite right : /

Actually using the screen was a better idea than you thought--It's already perfectly lit. With a real bluescreen you have to work on the lighting a lot to make sure the sheet is evenly lighted.

but the object itself is blue at this distance. but if it was further away it would be perfect.
