Dang dang...I hope you bring it back because I already have special news in using 3ds format. Using the free Gmax modelling program is great and suit for your WME. Using 2d characters in a 3d world is also possible, and is very astonishing. For example if you checked out RagnarokOnline ud be impressed of what you can do with WME, well with a few features I know of that I may suggest in sometime.
It has a responsive rotation system that also rotates around the 2d image, its obvious how the 2d character should work. They also have a well made options and menu system that is only really a mere 2d image that can be customized as well. In WME im sure the additional feature to making menus will also specialize in being able to loop animations; for instance the small statistics window it will be slowly shining from top edge to bottom. So im really knowing good RPGs will slap out from your trusty ol' engine.
As well as FPS will tour in, but Im also wondering if your problem with 3d models is that you cant adjust camera views and such??
When you release the 3d feature again, please please announce it.
I will help and give some pointers if you need any.
Continue the good work
