I looked over the tech demo for the commercial version and noted some things the Devs might want to correct.

1 - Going into the weather room there is a crash, the message is: Crash in roomP_startRain: snd_play (snd RoomPRain 2,100) and the sound gets louder.

2 - In the water room, if you move out into the water to swim, in 3rd person view she is half way above the water and when you stop moving she just hangs their in swimming mode. The characters body should be mostly under the water with her head up and when stopped she should drop to a upright 'wadding' position. Arms moving front ot back to keep her floating.

3 - In the Light room, thats beautiful except when the mage starts shooting fireballs his arms are at his sides, his arm should be up when he lets go each fireball.

4 - Also the ground should have a finer texture, it looks blurred and unattractive.

These suggestions will made the demo much better.

This demo is very old, as discused in a tread before. Maybe conitec or the community will make a new one.

It's a veeerry ooold tech demo, that were made back on A4, I belive...

EDIT: Ahh...2 minutes and I didn't see your post before I post it...

That is the old tech-demo. We've moved on to the Future level that is part of the template tutorials.

I'd love to hear some feedback on Future. Currently we are updating the shaders on it, but there should be more...

From just my point of view :
The entire demo should be redone and by two or more professionnal skilled artists and some skilled programmer.

The level is really outdated and have very poor dans bad 3D art, simple textures not homogenous at all taken from the bad standard Wad.
All people know that advertisment is very important , for 3D the eye candy and 3D art quality is the key.

But perhaps the goal of the demo is not showing candy things but functionnality ??

I've just said like always what i think
