I'm having an issue with my tree group setup. In my layout I have the tree (600 pixels) and the star (50 pixels) and 2 mini trees. The mini-trees are just a short string of dumb nodes. 3 channels each. All three are in my main tree group. I have noticed at times some effects do not work in the main tree group. Is the position of the main tree group critical? I have one sequence that is first in the line of the three models and another in is after the three models. Some times the effect chosen does not seem to work in the main tree group. Thanks.
