Yes it's possible.
One thing is sure: depending the exporter you ou use, for a same mesh contructed with the same method on 3 different 3D app ( in my case maya6, blender and lightwave 10.1 ) you often have different result ( specially with polygon smoothing and normals ).
The best of this three exporters is the blender one ( v1.10 from yoyo, with very good polys interpretation and many keyables parameters, DOF object following etc... ).
The last lightwave ( v0.4 ) one is very buggy ( very bad smoothing and normal interpretation ) and i use the 0.3 version, but it is slower for exporting and there is no animatable parameters ( like dof...). There's some ennoying things too: when you launch an animation computing, impossible to stop it ( execpt hard shutdown of lightwave with taskmanager

)
It would be great to make a 'chart' for programmers to unify the good functions ( with anim parameters ) and the same name, corresponding to octane( with same names, ie in maya, the 'focal depth' is in fact the 'fov' of the camera, it's quite confusing... )
