flipping objects with target-tag (c4d)

#1

Hello,

currently I’m modeling and animating a LEGO technic car. But i have a problem with the engine.

I animated the camshaft with an xpresso tag (autorotaion). The pistons are subordinated to the camshaft. I put on each piston a target-tag and aligned them to an null-object. All this works pretty fine. But when the h-angle of the pistons reaches the -90 or 90 mark, the piston flip by 180° and the h-angle is counting backwards. So the angle fade between -90 and 90.

I have this problem similar at the steering axle.

I have no clue what i can change.
