At first it seemed not too difficult to tackle the following problem, but in the end I did not manage to do it. Rotations are the story of my (second) life :-)
The problem: I have an object consisting of several prims. When someone touches the object i would like to point one of the childprims to the avatar who touched the object. See attached picture.
The rotation of (only!) that childprim only need to be done around in its XY-plane, so only a rotation around its Z-axis.
Does anyone has a working solution?
Thanks in advance for any help.
