Phantom prims cannot be linked?

I already build a long time in sl, but yesterday I saw that phantom prims, when linked, are not phantom anymore. What's even worse is that, when I unlink them again, the former phantom prims can't be made phantom again.

I can understand that, because other prims in the linked set aren't phantom. But is there a way around this? I need this feature for a frame with three curtains. The frame is not phantom, the three curtains must be phantom.

I've noticed that if you link a phantom prim to a non-phantom prim, the phantom prim looses it's phantom feature, but. If you unlink them, you can make the phantom prim phantom again. It seems that you can't link phantom and non-phantom items and retain the phantom feature.

Phantom prims can not be linked to non-phantom prims, If you want a phantom door, it has to remain a seperate item, like a chair or any other piece of furniture.

Phantom and non-phantom objects cannot be linked together. This is a hard rule of the physics engine. It cannot understand how part of an object could be tangible while another part isn't. It's either all or nothing.

Back in the days when it looked like Havok 2 might actually be a real possibility for SL instead of a punchline, LL had said that the updated physics engine would be able to to deal with partial phantoms, and reiterated that the current one absolutely cannot. That was years ago though, and today we're still using the same old antique with all its some old limitations. Don't hold your breath for that to change.

For your curtains, you've got three possibilities. The most obvious one is just to leave the frame unlinked from the curtains themselves. There's not really any reason they need to be linked, is there? The other options are to link it all and have the whole thing be either phantom or tangible. I'd suggest just making the whole thing phantom. What benefit is there in a tangible curtain rod anyway? It's not like the curtains actually need to hang from it physically.

Pffff Chosen, this MUST be the most obvious thing that I overlooked during my time in sl. Really, I was so concentrating on the phantom issue, that I totally didn't think to make the whole damn thing phantom. Well, I'll do it now. And anyway now I'm sure what can and can't be done with phantom prims. Thanks to you all!

This is hopelessly wrong. It gets you a phantom multi-prim object, is what it does. I realized that, though I had done this --the linking part-- I had not checked whether or not it made the whole thing phantom. It does. This time, I checked.

"Nevermind," says (your friendly local) Rosanna Rosannadanna.

The original and terribly erroneous advice:
If you want some portion of a multi-prim object to be phantom, make that prim Flexi. Flexi prims are phantom prims, but they may be linked to non-phantom prims freely. Of course, if you don't want it to flap in the breeze or sag due to some body force, make it very stiff, insensitive to wind, etc.
