FOSS gamedev and creative worlds

Has anyone made a code that brings in a 3D mesh made on a program such as Blender? Just wondering, because if someone published it, it would open up a whole new opportunity with mods.

Yes. It's nearly finished but I need help from someone more experienced in the code to nail down the remaining problems. After that I'll be making a 3D player with animations, but first I need to finish the code. http://minetest.net/forum/viewtopic.php?pid=49642#p49642
