Phantom vs. Physics Shape Type None

[Jennifer Boyle]

I have some prims that must not impede avatar movement, i.e., avatars must be able to move through them, that are phantom prims.  It would be convenient if they could be linked to non-phantom prims.  If I could make the physics shape type none, I think I could link them to regular prims without problems.  Would there be any disadbvantage to doing that?

None that I know of, I do it all the time.

Physics Shape Type None will trigger mesh accounting for the entire linkset. Depending on the prim types involved, and their Physics shape type (Convex Hull, or Prim) this can lead to higher, or lower land impact numbers.

So it can be a disadvantage, but also an advantage regarding land impact. Performance wise is type None preferable, over phantom. Because a phantom prim will still be calculated by the physics engine.
