Coloured spec maps
So we've been told in the past that coloured spec maps are better..because.... Well, here is the thing, I was trying to write a tech docfor 3d palette discussing the use of spec maps (as part of a mapping discussion) - what they are, why we use them, but I could find NOTHING on the difference between black and white and… -
Re: Coloured spec maps
You can make "metallic paint" stuff look really cool with coloured spec maps. Also iridescent stuff. For an iridescent beetle, say the diffuse colour is dark brown/black, you could give the spec a really saturated green colour, and that would give a really cool effect in game. Likewise metallic paint for cars... generally… -

Hey Vig for a nice example you might grab Harl's Worldsoldiers skinpack for QIII. I remember he actually painted multiple instances of head textures and blended/animated them with a shader. I think the avatars he did for the selection screen also had animation support, freaky Eric, yes I went for a painted-on specular for… -
Re: Coloured spec maps
This is off topic but how long until we have layered, animated colored spec maps that play durring certain animations? How cool would it be to see a charcter blush when they are embarrased. Or Watch a soldiers face drain of color before going into combat, or when he is shot and dying, watch his face go white. I wonder if… -
Re: Coloured spec maps
are you just talking about skin? different types of objects have different physical qualities that may result in a different reflection effect. all metals, for example, have a colored spec hit. blue metal, blue spec hit, etc etc. didn't everyone know that? am i missing something? -
Re: Coloured spec maps
Rick: Make/find a normal-mapped human face texture with a metallic iridescent green necklace or something, render one with a greyscale spec map, render the same angle with exactly the same textures but a colour spec map (make sure it looks GOOD first!), and put those side by side in your tech doc. Let the reader's eyes do… -
Re: Coloured spec maps
See, THATS the stuff I was looking for! Per, the opposite colour thing is what I was looking for, an explantion of why blue was used in skin, not just "use blue" KDR, Again the stuff I was after. I mentioned in my very first about it emulating the saturation at the terminator, but I wanted some backup, and thats the stuff… -
Re: Coloured spec maps
i think the question 'does it matter' could be said about a million things that we're doing in next gen games. I do however always promote the usage of color in spec maps, just because it does help at a bit of detail to your objects. I remember one good use a few months back was to add metal flakes to some stonework. The… -
Re: Coloured spec maps
As far as why blue specs on skin tones... what Per said. To further, straight skin tones look very zombieish. Making the skin color redder than it should be and using a blue spec makes for a nice translucent feel and you should really have a redish shadows and greyish hotspots. if it's a violent blue you've probably gone… -
Re: Coloured spec maps
I wouldn't say one is better than the other, but colored spec gives the possibility of creating a wider variety of appearances for materials. For example, my dad paints autos and motorcycles. One car recently had an orange finish, but a metallica purple glitter in the sun. I could have an orange color map, with a noisy…
