I do understand that Vue 5 has the multi-pass capabilities. But let me clarify what I how I would handle this scene...
What I would like to do is model a city in 3ds Max, animate a camera flying through the scene, then render the animation of the city geometry in Max.
Next I would import that whole model scene into Vue, then match and sync the camera path with Vue's camera.
I would then place a bunch of trees in the scene with Vue, possibly using the ecosystem.
In Vue 5 infinite, Is it possible to place a matte/shadow material on the whole city scene, so that when it renders out the animation, the trees would be masked out where they fall behind the buildings? I would also need the matte objects to recieve the tree's shadows.
Both the city pass and tree pass would be composited in Combustion.
Is this workflow possible with Vue 5?
