Please make sure it's the
correct PCS 2.1 (
this one), and not the one from
this thread, which links to a version that spits out buggy models on DAE->pmf/pof conversion.
I really wish someone would update the sticky, or un-sticky it, because the last thing I want to hear is people complaining about lag when the ship explodes, rapidly spinning debris, and/or other crashes that result from using that version which likes to set radii on random subobjects to arbitrary small numbers, and sometimes even
negative numbers (yes, negative radius...which by how FSO uses radii, is entirely non-physical...hence crashes).
