One Pixel Gap In Matte

Compositing
1

hi,
hi i am a 3d compositor. i am working Apple shake 4.1 currently i am facing one problem
i explain you that i am getting one character with fur and cutt matte to do CC. but problem is that i am getting one pixel gap when i use switch matte to extract Character with matte and because of that i am getting some transparency in image.
i will give u detail of rendering.
rendering software - maya 7.0
compositing software - apple shake 4.1
render size - 2K

assuming your matte has been rendered properly i would guess it's a premultiply problem.. have you looked into that?
otherwise you might try to mess around with dilate/erode or some of the matte control macros here, but it would be best to find out what went wrong with the matte in the first place.

HI,

Even one of my friend faced the same problem, then it was unpremultiply and premultiply problem, and also check your antialising values before rendering in Maya.

For Premultiply information, shake user manual page 420.
