Geometric Shaders

[Seven]

Can geometric shaders (or "normals") be used in game in JKA?

[Asgarath83]

Sure!

Check this tutorial:

Not for models, atleast outside of rend2

[Langerd]

It is good method but to be honest.. it rly take a lot of space on your map..

[Xycaleth]

Bumpmapping on maps doesn't take up any space.

It doesnt ? It took more time on one map to work for me D:

[Xycaleth]

More time doesn't mean more space It would take more time because it needs to read from the normal map texture, but the size of your BSP would be the same as if you didn't use bumpmapping.

Good to know that :3

 

Now i will check this method on my map as well ^^

Is there a working rend2 release yet?

[Xycaleth]

Working or release-ready? There's a working version, but I wouldn't consider it ready for release.

What is the text I have to put in the shader file for normals?

textures/amace_leviathan/wall3
{
     q3map_normalimage textures/amace_leviathan/wall3_normalmap
     qer_editorimage textures/amace_leviathan/wall3
     q3map_lightmapsamplesize 1x1
{
     map $lightmap
     rgbGen identity
}
{
     map textures/amace_leviathan/wall3
     blendFunc GL_DST_COLOR GL_ZERO
}
}

example shader

q3map_normalimage "path of texture"

not in rend2

Then what is it in rend2?

I think my Murasama model includes a rend2 .mtr file, go check that out - I'm on mobile right now and can't check it for you

[minilogoguy18]

My AT-ST includes a .mtr shader file you could use as a reference that Ashura wrote.
