I'm having a weird issue with a shape tween mask and a 3d layer. When the 3d layer uses the mask it seems to lag like 60 frames, but when it doesn't use the mask it plays normally. I've hosted it on my google drive at https://docs.google.com/file/d/0Bxlt52g6Mph9YWs1cnlBcGJxblk/edit?usp=s haring If anyone could help me out I'd be indebted. This project is due very soon and I need to get over this hump. I've named the mask in this case SHAPEMASK and the object it's masking is called COMPUTERSCREEN. When I mask COMPPUTERSCREEN with SHAPEMASK the timing plays differently than normal.
