I cheked it out a long time ago, I wasnt able to run any maps tho.
Not sure if it was my computer or if I didnt compile them correctly.

But it did sound pretty amazing.


EDIT:
I found about it from this thread:
http://www.quakesrc.org/forums/viewtopic.php?t=7074
One of the Xreal developers was making an RPG game with a heavily modified version of the engine.
Too bad it looks like he stopped working on it tho

Thanks for the link Cobo, that was very interesting.  I noticed Jitspoe even posted there, maybe he can fill me in on some more info about the XReaL engine

edit: I got the maps to compile by downloading a few opensource libraries, compiling xmap.exe, then running xmap -map2bsp <map name>.

Although, I had to use the visor model from my Q3 installation,

Anyway, it looks fantastic, despite not having any textures yet..


Edit again: after asking in IRC for the textures, they gave me the directory for maps and textures.. and everything else you need to get up and running, so Cobo, knock yourself out

I guess I might give it another try in the future.

You ought, ViciouZ and I got it running and we played a little on one of the dedicated servers.  I love that engine..

[Cobo]

I bet it would run pretty crappy on my computer, tho

[ViciouZ]

It runs about 11fps on my box and mine can run bf2142 at 60fps

It's certainly a nice engine.  I've been meaning to play with it.  Unfortunately it's a next-gen engine, and not extremely optimized, so probably at least half the people in this community wouldn't be able to run it well.
