Thank you for looking at my question, your support is very much appreciated. 
:rolleyes: I have a 6 second scene(with different takes and shot ofcouse) in which actor(half nude) is thrown into a acid drum and he comes out with burned fleshes of face and body area ( actor have chroma paint on face, shoulder and stomach area as you can see in this video -
http://vimeo.com/19618819 , i need your help to get real outcome, to make burned flesh on acid affected area what would you suggest ? how can i make burned flesh more realistic and how should i track chroma points ?
p.s. I am using after effects for this particular scene.
Thank you again for your time. :bowdown:
