Re: Color and Specular Maps
> To fake/bake a world reflection, blue sky on the parts that point at it. Brown/black for the pieces that face the ground. Works great when you bake a gradient over the top of your model. > To fake/bake sub surface scattering, to a minor degree since the materials color could effect its spec depending on what type of… -
Re: Color and Specular Maps
Ironic, that the post right above this one (as long as it stays at the top of the forum, which won't be long) deals with just this question. http://boards.polycount.net/showflat.php?Cat=0&Number=81058&an=0&page=0#Post81058 Specularity is the light shining off an object. It's a faked reflection. With a black and white spec… -
Re: Color and Specular Maps
They do for sure, but a follow up would be couldn't I just use a red light on that Christmas ball to get the red glow? (assuming I'm using a black/white spec). edit: Although to answer my own question, I guess if I used a red light I'd have red on the background layout too (red indirect light bouncing off the ball too).… -
Color and Specular Maps
I've done a quick search around here/net and I can't find too much as far as an explanation of what a specular color map is, or how to go about creating one and what colors to use. I'm used to using specular as a greyscale type map. Can anyone point me to a good resource for specular maps specifically color ones? I'm… -
Re: Color and Specular Maps
(edit)- As kind people have pointed out, "Linear Dodge" is Photoshop's mode for additive blending. You can use that to see what color your specmap will produce when added to your diffuse map. To calculate an additive blend yourself, just add the components of two colors. Thus Red(255,0,0) plus Green(0,255,0) equals… -
Re: Color and Specular Maps
Hey Saidin, Not sure if you already found a source for this but I thought Id give it a try. -A color specular map(this is my definition so someone please correct me if I'm wrong)is a map used to allow the light on a surface to bounce off and create an illusion of specularity. A classic example is the light that bounces off… -
Re: Color and Specular Maps
Yes, an apple under red light would look similar to a metallic sphere under white light. But if you want both in the same scene, you'll need colored specmaps. BTW, on second thought you might achieve a really white highlight on the apple by using an aqua specmap. Because specmaps are additive, and red + aqua = white.… -
Re: Color and Specular Maps
the best way to predict is honestly to view in your 3d application , because lots of engines interpret specular maps differently, also depends on shaders etc, what you texture for 3ds max might be different for uengine etc , depends alot man. -
Re: Color and Specular Maps
So one last followup here. Is there a way to tell in photoshop what my specular is going to look like on my model? I know we're talking about using linear dodge and thats PS equiv to additive layering and such, but how do I use that knowledge to pick the right colours for my map. I've seen speculars look like what I would… -
Re: Color and Specular Maps
Hello, Are these the only reasons you would use a specular colour map? >To simulate metallic or iridescent materials. >To counter-act the additive nature of speculars.
