Asmo and I almost never model in O2 Morpheous , thats why he wasn't really too familiar with the problem......
Instead of going through and making your points, then making those points into faces, etc we basically make primitives and then edit those.... (i.e. making cubes, spheres, cones and cylinders)
Instead of making a 2d drawing which you then make 3d later, we start with 3d objects and shape them how we want...
Since O2 was made by BIS for OFP , and it has the ability to import 3DS files, I would imagine that most of the official models were created in 3DS.
O2 is all right.. and it does the job, but all in all it really is a subpar modelling/texturing program
In the near future I can see us using O2 only for the memory/fire/geo LOD's
and doing all modelling and texturing before it even gets to O2
hope this shines some light on our modelling methods
