Textured Lights possible?

[WJTW]

I am wondering if textured lights are supported in JKII, because textured lights look better and more natural than normal entity lights, as I've seen in some other games.

 

Thanks,

Sure they are supported- just use a shader similar to this:

textures/textured_light/light2k

{

qer_editorimage textures/textured_light/light2k.tga

q3map_surfacelight 2000

surfaceparm nomarks

{

map $lightmap

rgbGen identity

}

{

map textures/textured_light/light2k.tga

blendFunc GL_DST_COLOR GL_ZERO

rgbGen identity

}

{

map textures/textured_light/light2k_blend.tga

blendFunc GL_ONE GL_ONE

}

}

 

 

Now just make two textures- 1. the texture to be displayed on the light and

2. a texture showing a) the areas that the light should come from and b) the color of the light

[Gignatz]

yup.

and to make the light that the shader emits coloured

put:

 

q3map_lightimage textures/mytextures/mytexture

 

after the q3map_surfacelight line

 

the compiler will take the texture specified and take the average colour and colour the light that colour. Try:

 

q3map_lightimage textures/colors/red (to emit red light)

 

to see what i mean.

Hmmm... seems difficult. Maybe I cannot visualise the process.

 

Does anyone know any tutorials regarding this?

 

And the JK2Radiant tool is quite tough. Resizing and selection objects is not even drag and pull, point and click (respectively)... or maybe I've done something wrong.

A good resource for shaders is Q3A Shader Manual.

 

I would suggest that you look at some of the light textures and their shaders that came with the game and learn from them.

Well, you could use Q3ASE as a help, because it shows you pretty much how your shader will look once you've got it ingame...
