check in here if you're interested guys. 

I think a mod needs to be set, otherwise this is going to be a real nightmare to install.
Also I am absolutely in. 

Not sure about rules/techniques, but I'm surely in! 

My mind is drained from the previous jam so I will not be participating. I look forward to the worlds that are created from this theme! 

It's just a shame the quake palette's grey ramp is so terribly coarse. If everyone's making new textures anyway, might it be an idea to use external textures without the palette restriction? 

scratch that fellas, the people have spoken on #tf and demand AD, so we're using that. 

how about packaging it with a custom palette.lmp so that enemies and guns and HUD are also greyscale? 

and you would benefit from more shades of grey that way, and you could use any 8-bit textures you wanted and not worry about converting them to greyscale individually. 

I've been doing value and color tests with grayscale textures then later adding various color themes.

I think this is an awesome map jam idea, not sure I'll have the time to break away from my own project though :/

Really looking forward to playing these and learning from the cool ideas I'm sure they will contain. 

Kinn is right, quake gray ramp blows. I have a 32 shade palette with a mid/low mid focus that might work well for quake. I can upload that or a couple texture tests using that palette if people want to experiment with it. 

If I was experienced enough, I might have given it a try, but I still have much more to learn before attempting to release anything. Here's hoping to see Rick's bar from Casablanca in Quake. Good luck to everyone who'll be participating in this jam. 

I think this theme is awesome.

Is a "sepia" palette allowed ? 

can you post some screenshots of it used on a map / hud?

I'd like to keep the coloured fullbrights in case people want something to stand out from the B&W 

Sorry, a little too restrictive for me.

Fire and Brimstone was good. Pipes and Water would have been good. Pipes and Water, must be Quoth, must be Base theme, not so good. 

THIS! is an awesome idea. 

if you want to use sepia, then use truecolor textures in your map. I don't think it will be easy juggling too many palettes. 

I'm abroad currently, but I'll return home at the end of the week and I'll upload some screenshits, the palette and some textures for people to play with. It may or may not save some people a little footwork.

Yep, that could be lovely. 

LMFAO!! 

Don't want to rain on your parade, but you'll have severe technical problems trying to use a custom palette with Arcane Dimensions.

Rather than ruin all the fun, I let someone else figure out the "why". 

(But a couple of small tweaks to Quakespasm will make everything "ok") 

Would need multi gamedir support (-game ad -game jam8) 

Winner!

Otherwise someone must choose that all AD games be black and white ;-) 

DP does multi gamedir.

To be honest, judging from the comments here I expected those screens to be a lot worse. I'm sure a custom palette wouldn't hurt, apart from the technical troubles of implementing it, but I think that's perfectly serviceable.

Anyway, If I find the time I might give this jam a shot. I flaked out of the last one quite early, but it'd be nice to take a break from working on Lava Bloom to whip out a quicker, simpler level. We'll see.
