well, I forgot to say that the engine DOES support normal mapping, parallax mapping, emitting maps. And it prefers hi-res textures :)
Unfortunately the maps used in the shots don't have neither hi-res texture nor normal maps, so some stuff cannot be seen. Only in the first shot normal mapping and emissive lightning is used, since I was using quake-retexturing project textures.

<>to introduce here my own engine made from scratch.</>

where is the engine?

:) 

Since there is not a stable version yet, I'm not letting anyone to download it :) As soon as there will be one, I will notify to all of you.
The fact is that I don't want people to see something that doesn't work well.
So sorry :'( 

It has nice eye-candy that does not seem to stray too far from the standard Quake aesthetics. I'm very interested in seeing more, but I support your decision not to release half-finished work. Keep at it, and if you need playtesters or have questions about Quake in general, let us know. I'm sure there are plenty of people here who would like to help out when it's time. 

It has also a basic physics system (quake-like), writen by me, of course, but maybe in the future I will switch to some library. And it has a basic AI.
It implements all the basic weapons, like pistols, shotguns, rocket and grenade launcher. However, everything is possible.. for example I'll make the DukeNukem3D weapon that resises the enemies :D

So you're not using the game logic written in QuakeC (progs.dat)? 

Sounds cool. I'd recommend Kell's texture set based off aliens (I can't remember the name) and maybe the snow tex' from Ogro.

Currently working on something so can't help I'm afraid.

Good luck.

Thank you for your appreciation :) Actually, the only quake-base engine that supports real time shadows and per-pixel lightning is DarkPlaces as far as I know. Besides, my engine is NOT quake based at all, so except from the assets I'm using, I would say that it's different from quake style. It's a completely different engine.

@onetruepurple: not at all. As I said, each line of the code of my engine was writen by me. I'm not using anything writen by others. The only things I'm using from quake are the assets, NOT the code: so only map and models... that is, the arts. In fact, I'm not an artist/mapper. And even if I would be, I wouldn't have enough time do to everything :D

I wrote here to know what people would think about my humble work, and because I'm testing it with quake stuff.
Plus, I really would like to make some sort of game, I mean, a game with a similar quake gameplay and stuff, but running on a completely different subsystem. Honestly, how much are the chances for me to find some mappers that could make some maps for themselves, and for me ? 

people have been grumbling here for ages about a modern remake for quake.

From those screenshots, this might be the way to do it. As sleepy said, seems to have additional eye candy BUT without deviating form the look and feel of the quake aesthetic. And the rest of the listed featrues seem desirable too. And I know RemakeQuake is in the works, but its still going to be based off an existing quake platform.

NiG, to be honest, I am not sure you will get much interest until a playable version of the engine is available so that mappers can see it first hand to know what it can and cannot do. Also, I think you need to provide mroe information about what formats of assets the engine can read.
