Is it necessary to convert all of the above file formats into .pod before including them into Cocos3D? It seems like that used to be the case based on what I've been reading but most of those posts are from several years ago and so I am wondering if it is still valid.
So my question is two-fold
1) If it is possible to load in these file types directly, how would I go about doing that?
and
2) If it is not possible and I have to conver to .pod, what is the easiest way of doing this?
