There's an existing issue of 2D art being difficult for many users. How would they cope with having to make full models for everything in their game, I wonder.
QFT
I Know I can count on one hand the members of the forum that i KNOW can do 3d modeling. and even then only a few of them can do 3d characters not to mention the rigging and the texturing.
3d in the industry still has almost no engines that can do everything most engines are made for one game and then are modded by other studios to suite their needs. as others have stated a WYSIWYG 3d editor would take a lot of time and effort.
The other makers have support for 3D, even weak
what other game makers are you talking about. and there is some 3d support for the 3d box.
people like me who are okay at graphics but not so good at other stuff.
You might be good at graphics but can you do 3d graphics and if you can can you do rigging and texturing?
I would be more than happy if you eventually enabled New Super Mario Bros. style graphics, though.
you could do this style now it would take alot of time and work but you could still do it.
