Rotate a Rotator? Gear to Gear 90 interp?

I want to set a gears rotation that is 90 degrees from another gear using the other gears rotation. What is the best way to go about this? The other gears actor is rotating, so I can’t set it from the mesh’s relative rotation.

You want to simulate the motion of miter gears?

You would have to either drive both gears from the same animation, or you have to build a custom physics join constraints that transfers the rotation.

Im driving a shaft mesh rotation with a timeline, the first gear actor is attached to the shaft mesh component. I want to rotate a bevel gear like in a gear box that is 90 degrees from the first gear.

Drive the second gear from the same timeline, then!
(Same time input, second rotation output)
