The best shadering parameters

[Asgarath83]

Well i am ending the Blades for my mod. After i need to do a looong shadering work about every sword and every character for make the best graphic and the best realistic result.

I know today people look graphic as gameplay.

How can i set the .SHADER file for create the more spectacular shadering about swords, blades and characters? I accept any kind of suggestion.

If you know the proper way to make a specular texture, I'd definitely do a lightingSpecular stage. tcGen environment stages work pretty well too.

 

Example:

 

textures/blerp/sultra_armory_metal_tank_storage

{

    q3map_editorimage textures/blerp/sultra_armory_metal_tank_storage

    q3map_normalimage textures/blerp/sultra_armory_metal_tank_storage_nm

    q3map_material solidmetal

    q3map_lightmapsamplesize 1x1

    q3map_lightmapMergable

    {

        map $lightmap

        rgbGen identity 

    }

    {

        map textures/blerp/sultra_armory_metal_tank_storage

        blendFunc GL_DST_COLOR GL_ZERO

    }

        {

        map textures/blerp/sultra_armory_pipe_spec

        blendFunc GL_SRC_ALPHA GL_ONE

        detail

        alphaGen lightingSpecular

        }

             {

               map textures/blerp/sultra_gloss

               blendFunc GL_SRC_ALPHA GL_ONE

               alphaGen const 0.15

               tcGen environment

              }

}

 

 

 

That shader above is for a texture in a level. However, I highlighted the parts you should look at. In red, you'll see the stage that applies the specular texture. Pretty important for a lot of weapon models depending on their material and how it should look in game/life.

 

In blue you'll see the stage that applies an environment texture. This is a texture to sort of imitate reflection, gloss etc...

Thanks, yes, for weapons i ever used the lightingdiffuse, tcgen and lightingspecular parameters, i see that lighting specular do the metallic reflecting and is very useful for the blades, and the tg_gen enviroment is useful for lucid surfaces, metallic, marbles, etc.

for rock and wood i think is best the bumpmapping.

but i never understand very much the language of shader file. so your link and your istruction are very useful. Tnanks a lot! ^^

 

rgb gen identity and the lightingdiffuse are good for flesh, hairs and dresses. Eyes need a tcgen enviroment. this is what i know about shadering with my experience, but i wanna see if someone know some other parameter that can create more realistic materials effect.

i will study the q3map2 shadering manual.

thanks a lot!

{

    {

        map textures/blerp/sultra_armory_metal_tank_storage

        rgbGen lightingDiffuse // proper shading for vertex lit models, or something. 

    }

        {

        map textures/blerp/sultra_armory_pipe_spec

        blendFunc GL_SRC_ALPHA GL_ONE

        alphaGen lightingSpecular

        detail

        }

             {

               map textures/blerp/sultra_gloss

               blendFunc GL_SRC_ALPHA GL_ONE

               alphaGen const 0.15

               tcGen environment

              }

}

 

 

Fixed for a weapon model like swords are

Thanks, Pande, well, in that's case, i am already using the correct parameters, maybe i need only to fix the alpha gen const.
