The missing link about Ramp map & shader

Cathodeus

Hello,

Long time ago i red something here on polycount about ramp map and the way it was used inside valve engine.

Do someone saved it to his favourite ? Can you re share it ?

Thanks in advance & merry xmas

Ah OK. Here's a link to the original PDFs.

Thanks for the link Eison, going to add this to the wiki!

I think he's talking about the reddish Ramp inside the TF2 half-lambert shader. I remember there was a post about it, including that PDF that valve released, but I can't find it now.

Download the texture pack full of ramps.

Just incase: TF2 uses it's own Ramp, DOTA2 had many Ramps for different hero's but half of them aren't used (they're basic HL as of now), and IIRC, HL2 and Portal also don't call in any textures.

Guys thanks for those link but it's not wat i remember. The page i'm searching showed how we can improve a wood plank material with just a ramp if i remember well. They showed how a ramp can be a game changer.

Should i saved it before ... i'm stupid :-(

Something like this?

Driver and some other peeps use this technique, there are a few threads in Pimp, but you first need to create the shader for it.
