once 3dgs flawlessly supports arbitrary level geometry i will do a blender (and probably also modo) scene exporter (with support for setting skills, scripts, lights, automatic recognition of instanced models, directly calling the map compiler and the engine,...).

i also will work on material support once i have more time again. i don't know yet how it will work. maybe there just will be some default shaders which will use the available maps and settings of blender's materials. or a shader network to hlsl translator but i guess this would be quite tricky.
