Rgb-cmy Matte Giving Edge

[user_deleted]

Hi all,

Im using RGB + CMY matte for my BG render in maya, this way in a single layer i get 6 diff matts, but when i use hsvtool in nuke to key the color to seperate the matte out, i get a white outline, is there any other way to do that, i have two more Gizmos also to do this job, 1) id\_select.gizmo, 2) iDMattePro.gizmo, all these three tools are giving me the same edge and also i have read, RGB color Mattes always will give edging because of it sharing the edges with other colors, so it has problem when it comes to deciding the transparency.

in the id_select.gizmo, we are using our coverage pass, but it still gives outline, but when we download the RGB matte and coverage pass that works fine, may our coverage pass setting is wrong... pls

so pls some one help me if you have any other solution

thanks
