[Opensim-users] Strange behavior of the llsittarget when the primitive is rotated 90? in X (Ferd Frederix)

[Luisillo Contepomi]

"as the sit target is relative to the prim, not the world.." This is
the problem. When prim is rotated in X (red axe). Rotation on Y or Z
are bad . Are relative to the world and I think this is not correct
behavior. llSitTarget must be local rotations no world rotations.
When prim is rotated 90 or others degrees in X then Y and Z are world
relative.  I think this is not correct. (But is a big problem because
when solve this I have many thousands of targets that I will have to
relocate.)
