Prims over island boundries

I'm building a bridge from one Island to another. It seems that the prim crossing the boundary from one property to another becomes something like a phantom. Has anyone encountered this and is there a work around? Its pretty annoying to fall through the bridge every attempt at crossing it.

i think, that the trick is to overlap 2 prims as follows:

Place one Prim with its center of mass located well inside one sim (maybe 1 meter from the sim border), but let the prim span significantly into the other SIM (maybe more than 1 meter). Do the same from the other side, thus both prims overlap at the sim border and span into the neighbour sim.

As far as i know, the overlap should span over the center of mass of the other prim. And maybe it makes sense to make these prims invisible, so that your artwork is not affected.

But i must admit, that this is what i heard, not what i experienced

You have to make the prim exist in both sims.

Easiest way is to make a transparent copy of the prim that's crossing the sim boundary and drag it into the other sim, attach a root prim at the far side (so it'll still be in the other sim when you drag it back) and drag it back. Now both sims will "see" a solid prim in that location and you'll stop falling through.

1: You can't share prim count from one side to the other. What is in one sim remains in that sim's resources, and that includes prims rooted in one sim but sticking over the edge into another. Where the root prim or center of the single prim is determines where it is counted.

2: Any prims that stick over the line into the next sim are phantom as far as the other sim is concerned. BUT, when you are going from Sim A to sim B, for a short distance prims rooted in sim A can still support you. This is vital to cross-sim building, because when you step over the edge, the sim you are leaving doesn't think there is a prim there for you to step onto, unless there is a prim sticking over the border from its side. So you start to fall through as you step across. So you need to do a prim overlap on the border. One prim that is linked to the other side, sticking over the border from each side. I usually duplicate one full prim in both directions, linked to the far side and textured 100% alpha, while the prim it duplicates is one with a non-alpha texture.

3: You can't link a prim in sim A to a prim in sim B. So to have an overlapping prim that is entirely in sim A and linked to a linkset in sim B. you have to link it while it is in sim B, then edit linked parts to slide it over the edge into sim A.

Keep those facts in mind, and yes you can build over a sim border.

All it takes is 2 extra prims, with one half of the bridge or stairs on one side of the border, and the other half on the other side. Read the above thread for my detailed explanation.

thanks for the info. I'll give it a shot and see what happens.

Just wanted to let you all know that by overlapping invisible prims it worked thanks again guys.
