Using Freestyle with semi-transparent materials I am working on an animation which will have a model behind transparent materials making up the foreground:



However, no Freestyle settings ("QI Range", etc.) are working for me. I tried setting "Edge Mark" and "Exclusive", but depending on the "Visibility" setting I either get the lines showing through the foreground mesh or being entirely hidden by that mesh.

What would be the optimal way to approach this problem?
Via Carlo's comment above (linking to this question), it appears that in Blender, "transparent faces are treated as opaque faces," so my setup would not work. Instead, I will separate the Freestyle layer.
