Hi,

I need to have the wind force work on an object falling when it hits a certain frame. Is this possible by creating a attribute that hold the y position for then to tell the wind force to start working when the object hits that y position?

Yes, use dopoption() expression fuction.

See attached file.

Thanks!
Im about to learn Houdini so I would prefer a more logical / easy way to do it.
Any other idea?
