While the FXTree is a pretty capable comp system, it can leave much to be desired compared to something like Nuke.
But the fact that it's stitched-on to a 3d app which other 3d apps still don't measure up on many fronts ... can make the FXTree like a fully procedural texture generator in one of the greatest 3d environments ever
Would have been great if the connection would have been both ways though, like piping the output of a camera, rendered on the fly or in hardware HQV to generate 2d elements from 3d. (in my dreams

)
What would also be great is if Redshift supported the FXTree out!
