fake bumpmapping to q3bsp

[Nahuel]

Hello forum, i have a question; How is possible to add fake bumpmapping to q3bsp? I did read many stuff but it´s not clear documents about this. another question, will work these fake bumpmapping in darkplaces engine or fteqw?? i don´t believe it, but i do not know thanks in advance!!

EDIT
I get it, it´s no so great, but is a nice alternative to get very high framerate without rtlight world activated

The only fake bumpmapping i've seen is precomputed lightmaps from normal maps in the Q3MAP2 compiler, and it doesn't look all that great either.


There's a GLSL patch for ioq3 (that OA implements as well) but no bumpmapping has come out of it.

Are you sure you don't want deluxemapping? That is fake bumpmapping, as far as I know.

yeah, i speak about the precomputed lightmaps... i know is not so great, do you mean these precomputed lightmaps work in ioq3 but not in quake 3 arena???

i use deluxemapping, works very good, but currently, i am experimeting with shaders, I was just trying to merge this shader with deluxemapping...
but I do not know if it works in some quake engine

How did you do it? As seen in the edit.

I use quark and quake 3 arena, first you need write this shader in baseq3/scripts/base_wall.shader

Code: Select all

textures/base_wall/wall3
{
qer_editorimage textures/wall3_norm
q3map_lightmapsamplesize 1x1
q3map_normalimage textures/wall3_norm
{
map $lightmap
}
{
map textures/wall3
blendFunc GL_DST_COLOR GL_ZERO
}
} 

after you need declare the shader to work in quark, you must declare it in
QuArK 6.6.0 Beta 3\addons\Quake_3\Q3Textures.qrk, you can open the file with notepad and edit it. For example you can write after

Code: Select all

base_wall/shinygrate1_4.wl =
        {
          a = "baseq3"
          b = "base_wall.shader"
        }

this new shader

Code: Select all

base_wall/wall3.wl =
        {
          a = "baseq3"
          b = "base_wall.shader"
        }

In the folder "textures" in baseq3 you need to put wall3 like diffuse texture and wall3_norm like the normal texture. in quark you can select the shader in "base_wall" (quark display the normal map like the image of the shader (qer_editorimage textures/wall3_norm)

looks nice, consdiering rtworld lights kill my fps.
