Lag Trouble

When I try to make a big animation it gets really laggy before I can even finish the first scene.
I’ve tried putting my scenes in a clip but it doesn’t work.

If anyone has any technique for solving this, please tell me.

You could make a new animation that has the details you want. Basically parts.

Also, could you send the wick file?
