Dear Operate;
You are men of considerable means and talent. Your name preceeds yourself. You are versed in things of a technical nature.
I... We have been working on a libre vidya game for some decades now. It has 200 weapons now, 30 official vehicles (and really 65 vehicles), magic, rts style town building (with interiors) (buildable buildings), some building with blocks and other shapes for those who like that, city generation, and nuclear weapons simulation.
Some years ago we sojurned onto the engine and decided to expand our stake there. We added 4 million entity networking (previous limit was 32k). Then we remebered we liked the Wolfenstine:Enemy Territory bsp map format.
That took a month to implement. It was an eye opener.
Later we saw the engine supported obj files as models in maps, but the obj files exported by minetest/c*aft and bzflag didn't work as maps correctly (bzflag's version of obj didn't display at all). So we fixed that and now you have options of .obj_from_mc and .obj_from_bz , and you can add scaling options .scale1024.obj_from_mc which makes mapping in blender easy.
Could you help us add more formats?
