XPresso Gears and Rotation
Hi all,
I’m sure this is an easy one for some XPresso expert. I’m trying to animate the classic gear 1-gear 2, and can’t figure out how to make gear 2 rotate in the correct, opposite direction as gear 1. I can build the XPresso that turns gear2 when I turn gear 1, but it turns it in the same direction. How do I reverse the direction? I can’t seem to find a node or input to allow me to enter a negative value. Can someone point me in the correct direction, cause the manual reads like stereo instructions and is not very helpful.
Thanks
Dan…

math node (multipy a negative)
a range mapper would also get the job done….you will have to learn that one when you start adding more gears./randy

Randy,
The range mapper bumps my gears out of alignment when I set it up. Not sure why that’s happening. I tried the Math.add and changed the node to multiply -1, but it didn’t work. Can you give me a few more details about this, please? I’m a little new with XPresso.

Ok, I see this now. Seems to be working for me. I’m going to try to add a few more gears now, so hopefully this won’t explode on me. Man, someone needs to write a really good book on XPresso. They’d make a fortune. 🙂
Thanks Randy
