Found some issues. After saving to dae and reimporting as pof, I noticed a few things missing. The glowpoint normals were reset to 0, the MOI was lost, and the overall scale seemed to have been changed ever so slightly. The last part may not matter much as long as everything lines but, going between dae and pof over and over and over is likely to create problems if that has to remain the case. But losing data completely I hope could be avoided. Of course, this may not really be the intent anyway, since it still seems the model and the bulk of its data were retained, which is fantastic. The scale problem could also be due to the changes to the POF export side of things now too as the starting pof was made with PCS 2.0.3 and this using the changes that have brought it up to 2.1 Alpha.
Also, when I open the file as a DAE, its size values are drastically different from those of even the output POF, which are much closer to the starting POF. I just found this bizarre, as long as the end result is fine it's not a problem. For example, the original POF had HWD of 79.46, 66.87, and 65.15. When I saved as DAE and opened the DAE, those values were 49.74, 54.80, and 61.24. When I saved that as a POF and opened that, the values were back to the original numbers.
