  • Cutting out images with a pen leaves alpha leak

    Posted by Alex King on March 18, 2014 at 6:07 pm

    Hello. Hopefully I came to the right place for help. I have several images that I am working on in After Effects ( CC ) that I will export to Cinema 4D. It is a rather simple camera projection scene in C4D consisting of trees and an addition of trees. When I prep the trees in AE by keying out the sky, snipping the top treeline with a pen, and eventually precompose the same image again, and render it as a still image with alpha, I have an alpha leak on where on the exact same lines where I was snipping with the pen tool. Is there a way to fix this? When it is camera projected in C4D and render with alpha, you can see the hideous pen marks that came over with the image.

    Any help will be greatly appreciated. Thanks

    Not completely sure how camera projected stuff works in C4D, but I had an issue with images I brought in from Photoshop into C4D.

    I was seeing stuff that shouldn’t be there.

    I found out that if I unchecked the ’tile’ setting in the surface manager of the object it fixed it.

    Maybe this will help, maybe not.
