Well, I found this shader in github time ago I do not know if this shaders are here yet, (shader are published in 2014) so it's an old stuff right now!!

A guy called hgsz upload this shaders to get a really retro style to darkplaces engine


you can find it here....
https://github.com/hgsz/retro_quake1


in the description you can find ....

This is a Quake 1 post-processing effect which intends to emulate lower resolution and reduced color palette.

This mod is for those who want a more "authentic" retro experience.

See high resolution before and after.

I think this shader is a very nice resource to certain mods like arcane dimensions
even to play crazy new mods (like smc plus effects).

in the cfg you can specific the resolution to emule and the colour range per channel.

the screenshots in github are not so good to show the effect, so i did upload some screenshots. The screenshots were taken with a resolution of 1080.


emulated: 320 * 240 , 8 colour range




emulated: 640 * 480, 16 colour range using qrp textures, quake style particles (blood is really nice)







Play with values, manily with brightness and gamma!


Please, avoid comments like "lol a new shader in a new engine to get an old look"... no dude, this kind of comments are not intelligent. Write your own glsl shader for darkplaces if you do not like it

No LOLs but I don't really see the point of using DP for a retro look.

if you are a retro gamer you can play some new mods, (darkplaces exclusives like nenhahra or SMC and more) with the old look.

i actually have a special DP setup for when i want the retro feel,
where i only included stuff like debugged and authentic-improved models and disabled linear filtering
and added a special particle-font to give particles taht old-school square look instead of the filtered circles

this could be interesting to add to that setup to simulate the look of a 256color monitor
to get a look thats even closer to how software quake looked

I like it!

@bfg

DarkPlaces supports a lot of things mods like to use, like updated HUD, custom crosshairs, disabling the camera tilt upon dying to allow for a death camera...lots of subtle things that add to a mod without radically altering gameplay. Really, these are things ALL modern engines ought to support, but don't. It's nice to keep the retro look combined with sensible upgrades. Mod I'm working on falls in this category. After wrestling with QuakeSpasm for a good long while, I finally decided to just go DP and maintain the faithful look. It's easier to do art work for the faithful look as well, especially when there's only one guy working on the mod and he has to be Jack of all trades, master of none.

I do not think that stuff from 2014 is "old". It is quite new.
I am old !!

Hehehe, that is correct.
It is always good to have additional options for a game to change it to ones personal liking. There are thousands files/mods/maps/etc available for this old game called Quake. Use the ones you want and avoid the others. Live and let live.

Best regards,

i got one question though about this glsl shader.....

it says to add a value for 'color range per-channel'
im afraid im not known with this type of measurement for colors?

i assume its an equivalent of how many colors are emulated... but what are good values for it?

like which value would make the shader emulate the look of 8bit/256 colors for example?

Hello talisa,

There is a nice page that describes the relation/link between color depth, bit per channel and color range.
This is for english speakers: click me
It covers color depths: 1-bit till 40-bit.

You will find links in it to each color depth with more detailed information for that specific one. You are interested in 8-bit color depth, so this would be the link for you: click me

For german speakes there is even a better page which also has a table with a great overview of all color depths, their color range per channel and the available colors. I suggest to at least look at it. You do not need to understand german for reading the table: click me
It covers color depths: 1-bit till 48-bit.

Best regards,
Seven

just wanted to mention that these shaders DO NOT seem to work in the newer 2016 darkplaces builds.

trying to use these shaders in the new 2016 DP builds results in the screen just looking really blurry instead of pixelated.

i had to downgrade my retro setup to an older 2014 DP build to get the visuals to look like how they should.

.

so a heads-up for anybody who wants to give this shader a try,
use a 2014 build instead, like the 2014-04-30th autobuild

Hello talisa,

I fixed the shader for DP 2016 builds. Find the download below.

Could you find the answer to your color question already ?

Best wishes,
Seven
