TECHREP #00005 Specifies the renaming of Oxygen2 to Objectbuilder, but mentions nothing about the removal of FBX Support, which in turn is not present in ObjectBuilder.
The FBX.dll is still present in the folder, could you please find your way to quickly hotfix the tools to bring back FB Support..............but in doing so please don't break the ARMA Tools again as it took me 3 days to get it working after the last update. {F23557}
