I am currently working on a lightsaber fight and so far so good, until I get to the point where the saber passes behind my head. I tried masking, but later in the film when I use it again it leaves a shadow where the previous one was located. How do I avoid this problem?

What do you mean by shadow? What does the shadow look like? Have you moved the mask from its original position, or is it still there?

If your on about masking aroudn the head but then when the lightsabre is no longer behind the head there's a slight opague type shadow? This might be because you don't have a background plater of the area you have just masked.

But can you send us a picture please?
That would help. wink

Ok ill try and put a pic so that you can see what i mean and try to help me solve my problem. I had 6 different masks for 1 specific section, and thats when I noticed that the previous masks would remain in the background causing a slight shadow effect, but I'll put a pic so that you can tell me what I'm doing wrong. And Thanks for the help!

I did that one time.
I think you just have to move the mask out of frame when you don't need it and then place it back when you do. you'll have to put a key frame of the mask off the canvas for the frame right before you want it back in or otherwise your mask will just float back into the frame. do the same thing when you're moving the mask out of frame.

Why do you need six masks for one scene? I can see two maybe three but six? Also make sure your not using too much feather on your masks that can cause problems too. Spyderhank probably gave you the right answer. I remember trying to use two or three sabers instead of masks... that was a nightmare!
