Final work : Compositing Flower, Sky and ButterflyFlow

   I imported Sky to Flower scene and tried to import ButterflyFlow as well, but my maya kept crashing whenever I import ButterflyFlow. To solve the problem,  I export the camera path from ButterflyFlow and import only the camera to Flower scene. Whole range of video is 500 frame. From 1 to 300 frame, I only rendered Flower scene and from 301 to 500 frame, rendered separately Flower scene and ButterflyFlow scene. 

    It won't look same as the storyboard I uploaded. The butterflies fly following the path so It doesn't look like flock, It looks like thin line of butterflies. I tried to make them as flock but it looked a bit scary. So I changed to make their path as narrow.
