If you could imagine a spaceship with a vertical mast coming down from underneath the ship with 2 various sizes satellite dishes, end to end, on the bottom of the mast. (Dishes obviously pointing out horiz 180 degrees to eachother)

When I built the seperate mast & dishes..made the mast the root prim and linked the dishes etc to the mast...it all rotated just fine.

When I link the whole mast & dish segment to the spaceship, which has the root prim in it's center (for flight/flying), how do I then get the dishes to rotate on the lower mast?.

Ive managed to rotate the mast around the Z axis but the dishes stay still..as they are now still connected to the mast, but the mast is no longer the route prim. I had put the slow rotation script in the mast before.

So now..I know I can rotate the dish by putting a rotation script in the dish itself (i think lol) but how do i get the whole assembly to rotate?. Assembly is 2 dishes (small & large), each dish with a center spike plus the larger dish has a little disc halfway along the spike. Am I limited to just having a 1 prim assembly rotating?

Is it anything to do with the order of linking? dishes to mast, mast to ship, ship to center root prim? (naa cant be..doesn't sound right)
Any help would be appreciated as I will be coming across this problem a few times with other projects

In SL's linked object groups, prims are relative only to the root prim, not one another.

To use llTargetOmega you will have to keep the mast a separate part, which is a toughie if the build moves.

The build does move..when finished, it will probably not be static very often lol
I tried the free version of puppeteer on the dish assembly but was very 'steppy' (understandably as it's not meants for smooth movement and def not smooth rotation!)

Being a non scriptor, ive come across what you would think would be small stumbling blocks but turn out to be huge headaches or impossible unless you get it custom scripted for you

It might be possible doing the assembly as a sculpty but will look alot worse, especially as one of the dishes is a mesh (alpha texture) so that same texture wont 'take' very well atall.
