PE3 is BobR's project to use the peX game engine. If you have issues with pe3, you musk ask BobR. If you have issues with the peX engine, then ask at
http://pedg.yuku.com/. There is a history between Bob and I that is a permenant rift.
I have found it difficult to support peX at GOG, so I have abandoned PE support at GOG.
We lost Wolf and we lost the TvT forum where most of the PE modders hashed out an agreed time line of the PE history. Ost won the propaganda war of the great creators from the PE wars.
I respect what the creators of OstPak made with there modder ability of that time, but they are not PP2, nor PEDG, nor P.E.D.G nor, PE-X. Ostpak are great scenerio creators and great 3D model creators, but little else ( my opinion ).
Ost, if you have an objection, then speak up. At it's end, we all seemed to agree on the TvT forum. Lets hash it out again if need be.
