Re: Simplest way to create specular map
If you want to go for the real quick and dirty desaturate diffuse for spec you might as well just reuse the difuse and adjust it's values in the shader. This way you aren't wasting a texture sample and graphics memory on a texture that esentially contains the same information as the diffuse. -
Re: Simplest way to create specular map
You can use the diffuse and simply play with the levels in certain cases, but adding extra info in the specular that the diffuse doesn't have, will give you better results. An example would be shiny wood with a varnish finish on it. You'd never use the diffuse as the base for the specular or if you did, it would be barely… -
Re: Simplest way to create specular map
That's the old school method for me too, flatten diffuse and save as spec, adjust levels etc. Now the psd's are kept in layers, once a good diffuse is made it's saved as a specular and then every individual layer is adjusted (levels, contrast, curves, blending modes and opacity) Most layers are desaturated except those… -
Re: Simplest way to create specular map
I tend to work on all my maps at once. If you think that the method of creating a specular map is to copy it from a "finished" diffuse map and tweak it, then you're probably wasting a lot of time - since the way specular can affect the look of diffuse really means you should work on both at the same time (along with gloss,… -
Re: Simplest way to create specular map
I wouldn't really agree with this being all that insightful(the first bit). Its just a couple of steps above desaturate the diffuse. Also no mention of a gloss map which is equally as important. Making a specular map is not something you do as an after thought, you need to structure your diffuse correctly so that you can… -
Re: Simplest way to create specular map
Well depends on the way which you used to create the diffuse. (at least thats the way I create my spec maps) I texture the diffuse in some 100-200 layer psd and use that psd as a base for the specular map in order to achive certain looks in it. By that I can adjust certain parts without effecting others and vise versa.… -
Re: Simplest way to create specular map
Taking a desaturated diffuse and slapping it on the model is NOT the way to go, but most people do start that way. If you are stating from a diffuse map then try the Filter> Other> Highpass rather that a straight desaturate. I've had success with desaturating a normal map and then selectively darkening areas of it. -
Re: Simplest way to create specular map
Well here's the method I use for mass producing spec maps. For single stuff that I want to show off or for portfolio work, or if it was for an FPS game, I'd take a longer time. But if I need to mass produce a bunch of them I use my quick method. Step 1: keep my diffuse in layers. Step 2: grab each layer, go to… -
Re: Simplest way to create specular map
Usually as I work I have a Spec folder, which houses alot of Layer Adjustments in it with masks for specific areas. Its good because it updates as your diffuse updates when your polishing. But when the diffuse is done I spend a few good hours on tidying up the spec map, making sure the right areas are specular and never to… -
Re: Simplest way to create specular map
copy diffuse, grab diffuselayers, adjust specmap! ps. dont forget the glossmap!
