As we are in a kind of "off-topic" thread, i would to say yes, is very interesting. I think that DOOM3 Engine`s, which is the same engine that powered Call of Duty 4 (althought Infinity Ward modified the original DOOM 3 engine), regardless being a little old and outdated (the id Tech 4), it has some good features, especially the lighing, shaders and ragdolls.
I do have DOOM III, i played it a lot, and i was amazed with the graphics, on that time.
I know DOOM III editor is the GTK Radiant, i have it installed in my PC (i used it to open Call of Duty 4 Maps).
I love to try level editors, i think is something very cool when you open the level the guys created, and navigate through it, is something very cool.
Now, i am porting levels from Source Engine to FPSC (through 3dsmax). I can say, i discovered a method of importing the level entirely with models, textures and even lighting to 3dsmax, then i bake textures and export to FPSC exactly like in Source Engine! I think it is even more beautifull than the original, because i use a lot of max plugins and scripts, to add some special effects to the entirely lighting.
I think if i can find a way to export levels from GTK Radiant to 3dsmax, i think i can port the entirely DOOM III game to FPSC! WOW, i think this would be awesome, don`t you?
By the way, i loved your DOOM III remake in FPSC, really, you replicated almost perfectly the level environment!
Congratulations!
