[Opensim-users] llTargetOmega : Bug or feature ?

[Leal Duarte]

Manual will "be strange" if the prim is already doing target omega.

not immediate clear what is the real rotation viewer applies to the 
actual prim (as seen by region)

also not clear what is the base rotation it will use if gets a new 
target omega.

your original code will make the cylinder rotate around its local Z 
axis, it you do stop target omega before changing the prim rotation and 
setting other target omega.
