Baller-coaster

I had had a lot of fun with making this “ballercoasters”.

It is where you have a ball wich rolling down a slide until it get to its goal!!

The problem is: I want to make some loops. but when i have a curve and a bevel object and the curve turn around in the loop the slide doesn´t follow!

Try it yourself with a cyrve and a bevel object!

How do easy make a perfect loop?

I suppose you could use a section or two of a sphere or a cylinder.

Yeah maybee i could!:frowning:

But i want to do it with a curve thats easier!!:cool:

Please help me somebody!:confused::confused::confused::confused:

THANK YOU:)
