I am facing many problems when creating the IK animation. My job is related to shipping business and i need to create working ship’s crane model with IK constrains. The task is look simple from first approach. So what I exactly need - the crane structure has to follow the cargo on the hook. The biggest problem for me is the rubber band joint where child object is always scaling with parent, in my case hook block is the child of runner(wire is rubber band ). Hook is set up as a child with rubber band joint and checked constrains with relax to motion and rotation - doesn’t help, the hook still scaling or ’ constrains goal is not reached’…
When i created similar IK connection with simple solid boxes and dots then everything works smoothly but never work with more detailed objects, even worse- it works unpredictable. Some other issues i listed below:
- Appearing the ‘phantom ticks’ - without activation of animation some movements start recording on the time line (no ticks shown),
- The model is not respecting the Limits
- The screen picture is not reacting on the objects settings in the real time, i have to click on the object and moved a bit to accept the last alterations.
- The object is not respecting the Relax Constrains menu in the most of the time with mashes or more detailed blocks.
