[BUG-5528] Flexiprims no longer become phantom in linksets

[sl-service-account]

Steps to Reproduce

• Create a regular Prim
• Create Flexi Prim
• Observe the Flexi becoming Phantom as usual
• Link Flexi to regular prim as a child
• Observe the flexi prim becoming non-phantom
• Expected: the flexi prim should remain phantom
• Switch flexi off, then back on
• Observe the whole linkset being phantom now
• Expected: Only the flexi prim should be phantom
• Uncheck phantom in the root

• Observe that now the linkset is non-phantom and the flexi prim is phantom, all is as it should be

  Actual Behavior

  I tried to link a flexi prim to a regular prim, but the flexi prim didn't stay phantom as it should.

  Expected Behavior

  The flexi should have stayed phantom.

Confirmed using Second Life 3.7.4 (288138) Mar 15 2014 16:28:23 (Second Life Release) on Second Life Server 14.02.28.287383.

Though it's strange. Certain prim sizes (and shapes?) wont repro this. Heres an example of a non-repro:

• Rez regular default box.
• Rez regular default cylinder and stretch cylinder to be size <1,1,7>.
• Make cylinder flexi and observe cylinder is phantom.
• Link box and cylinder with box as root.

Observed: Box is not phantom. Flexi cylinder is phantom - avatar will not collide with the cylinder prim. Edit linked parts though shows the cylinder as having phantom unticked.

The physics shape of the flexi is half the size of the visual appearance, which leads to teh assumption the prim was phantom, because you walk through the actually phantom half of the prim.

Hi Toy, thanks for the report. This change was made during the pathfinding upgrade in 2012. At the time, I filed an internal bug about the change (PATH-796, for reference), but the team decided to not preserve the original behavior (which is a bit of a hack). You can find this change in the release notes, here: http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Server/12#12.07.31.262785
