You may be right WandW, but that doesn't really make sense to me. If that is the case, then why are we allowed to put our runtime folder anywhere or to have multiples of them? If it is a relative path being specified as ":runtime:geometries:modern shoes" then it should not matter where runtime is located, as everything before that reference is relative. But I don't know, I'm not a Poser Programmer. :)

Anyway, I managed to fix it. I renamed all of the STZ footwear collection OBJ's to "STZ ShoesX.obj", where X is a number from 1 to 5 just like it was before. Then I edited the CR2 files and changed any reference to "ShoesX.OBJ" from its original reference to "STZ ShoesX.OBJ". That seems to have worked. Both shoe sets load correctly now.
