Quake3World

hey i've been making a map for a while now.

I've figured out how to get nopicmip on textures with the help of q3ase, etc

Now I've ran into a problem, I want to nopicmip a texture but when I do the
brush using the texture/shader I created makes the brush overbright, which I don't want.

heres an example of one of my shaders:
What would I have to add to it to make it not overbright when I run the map?
I want it to look like any other brush affected by the lights in the map, etc not be overbright, etc

you need a lightmap stage:

textures/xdc/xdc
{
qer_editorimage textures/xdc/xdc.tga
nopicmip
{
map textures/xdc/xdc.tga
}
{
map $lightmap
blendFunc GL_DST_COLOR GL_ZERO
rgbGen identity
}

}

thanks for you help, & the quick reply

but i still have a problem:

the floor texture is in the script 'xdc/base_floor' and it has flat lighting (the walls, floors, teleporters dont use shaders)

Now all the 'green outline' textures are the same exact color, but are now in different shades

Apparently something is wrong in the script since one of the larger textures won't nopicmip

this is before I used the shaders, see how it has normal lighting, etc

I attached the whole .shader file to this post

thanks for your help, once i get this ill be able to release my map

I *think* (not sure if nopicmip works with :q3map) this will work and greatly simplify things. It implicitly generates the rest of the shader in-game as it would with a basic texture and Q3Map2 just reads the compile time bits:

For your new problem, try removing the shader file, recompile, and see what happens. If it's fixed, try copying small chunks of the shader at a time back in. Repeat until the problem reappears, the last bit you copied in should have something wrong with it, check for typos or syntax errors.

I'm trying to figure out why a lightmap stage must be added but I don't get it, could you explain?

Think of a lightmap as a mask on top of your textures. When you compile light, the light information is stored in the lightmap. Your textures stay the same all the time. The lightmap is then projected on top of your textures to create the illusion of light and shadow. Without a lightmap, all textures have the same brightness level.

So the overbright is caused because the lightmap isn't applied?

Overbright and fullbright are different things. Without a lightmap you have fullbright textures with no lighting information at all. Textures with overbright have a fake bloom look. But I guess that's not what you meant. So yes, without a lightmap you have very bright textures.

Ok, thank you for clarify. Do you know a link which explain this kind of this things?
