The cross-fading system which goes from mesh to billboard and vice-versa is not behaving as I would expect. Once a cross-fade begins, it should complete in a set period of time even if I don't move any closer. Currently, if I move slowly toward a billboard tree it will begin to cross-fade, but if I stop moving then the tree is stuck in a partially faded state where it's obvious there are dithered pixels. When observing other fading systems in games as soon as the cross-fading begins, it completes within a set period of time (1-2 seconds) even if I stop moving.
