Oxygen 2 Personal Edition is the “O2 for ArmA”.

O2 has changed a bit since OFP times, now there is the rvmat texture slot, quite few more features and its buldozer is the ArmA engine (exe) itself, its quite nice in fact.

It comes with an exe installer unline its predecessor, it works quite nicely and setups the subst drive also.

If you want to enable your mouse cursor in the buldozer window so you can jump in and out of it without ALT-TABing, then find your ArmA.cfg file which the buldozer uses and enter there line of:

DisableMouseExclusive=1;

TODO… sorry.

If you want to export your O2 model into 3DS Max, add the dlls of the O2 light and export works with textures. Note that once you copy the dll's, you need to set the dll paths correctly in options and restart O2.

If you cannot apply textures, make sure you have downloaded the latest Release Candidate 3 (or later if available) as the first version RC2 had a bug in DLL directory setup that prevented you to apply textures.
