View Full Version : Strange Problem with constraints
01 January 2005, 09:22 AM
Hi! I'm doing a animation of a large crane for my employer, but I've come across a problem I can't seem to figure out. I'm trying to get the hydraulic cylinders constrained so that they animate properly. To do this I am using "TRACK TO". I select the bottom half of the cylinder, and the pivot point of the upper cylinder, and apply the constraint. No prob, works perfectly. The problem is that when I try to do the same thing with the upper cylinder, it doesn't work. Instead, the "const" box turns red, indicating a problem. I can orient it in any direction and it will work, except in the direction I need it to be in (which is Y). I don't understand? Any ideas?
