First, sorry for my bad english but I'm a french guy !
I'm working on a Flash app, where I have to show a car in a 360° view.
I use 3dsmax (Vray 1.50 SP3a), After Effects and Flash
Users should be able to change the color of the body and also (the hardest part for me !) the opacity & tint of the glasses.
I've found a solution to change the color of the body : rendering different elements (Diffuse, GI, reflections, ..) and a color correction in after effects.
But I don't understand how I can change the opacity of the glasses in a compositing workflow.
Obviously, I've tried to render a refraction pass but I don't know how to use it later..
I also tried with a MtlSelect pass but it didn't work.
Could you please help me, or maybe tell me where I could find informations about this.
Thanks in advance.
