I have an animation demo, as follow:
animation-demo.zip
animation description:
- 0-60 frame, the door opens;
- 70-100 frame,the three helicopters move into the red box;
- 110-140 frame, the door closes;
- 150-210 frame, the box moves to another position.
Question:
Between 140-210 frame, the three helicopters are in the red box and invisible, I think if not to render the three helicopters at 140-210 frame, rendering speed will increase.
Is it possible that not to render the three helicopters at 140-210 frame? If possible, how to do it?
