Hello All,

The dilemma is that I have a crane which is being lifted up into the air via a hydraulic piston.  As the crane lifts, however, the base of the piston’s main housing slides out away from the crane on a track to give it a sturdier position.  Is there any way I can link the position of piston base to the rotation of the crane so that I can easily keyframe just the crane and have the piston behave accordingly?

Additionally, does anyone know why my Look-At Constraints cause the objects scale to skew when closer or further away???

Thanks,
Jared

I’d suggest a picture...I’m not sure if it’s the morning fuzzy head or you’re description,
but I can’t picture what you are talking about.

As far as the skewing...probably non-uniform scale on one of your objects.

scale = evil. Uniform scale doesn’t misbehave as much, but as a general rule scale
causes more problems than the 10 secs it saves you to not do it at the node level.
