Hasta La Motion!

Currently I am working on a short film call "The Tree"
and Come to face few problems with compositing,

as far as i know I heard this is very basic problem that all the newbi will face, 🙁

anyway, I was wondering if anyone could help me to get around the problem.

The problem i am having is that I am trying to render the image in two sperate passes

1. Character
2. Background

but I am keep getting some sort of white(green) outline in the character,

please help me how to solve this,

Currently I am using 3Ds max rendering with Vray, Saving format as Tar files.

and Composting with DF

Node

Background Ambient light

Background Key Light

Character Ambient Light

Character Key Light

As Result

end up with White(Green) Outline Around the character (first it was white but I changed the background color to Green in order to make you guys see it better)

Thanks for reading my post:)
