Talk:Light Textures and Falloff Images

This article is kinda weak... I hope someone comes along and beefs it up...

Cumbersome Manual In-Engine Light Map Making

New idea:

No need for 3rd party baking tool...

1) Remove all direct lights

2) Replace textures with gray

3) Place lights in map the resemble bounces

4) Capture screen-shots

5) Use Image Editor (Gimp) to obscure all but the light patterns (bucket-fill and selection tools)

6) Blur and Smear (faked Radiance transfer)

7) Save as a light texture

Misc

Projected Ambient may be a good fit?

PostNew Horizon, on 09 July 2010 - 12:40 AM, said: I wonder if there would be some way for us to create a setting in the SDK to create a negative spectrum setting so that we could just tag a light neg_spectrum -1, and only have to tag the surface we don't want affected?

I've never tried it myself but it may be possible to pass entity parameters to the spectrum keyword. Something like this...

textures/whatever/mytexture
{
        spectrum Parm5      
        {
                map     textures/whatever/mytexture
        }
}

With something like that in place for all the textures you could isolate geometry into func_static entities and assign them to groups.

Negative Projection Light?

lights/shadows/shadow_circle_projected_01
 {
        map     invertcolor(lights/shadows/Example_Pre_Existing_Falloff.

tga)
        }
{
 blendLight
 lightFalloffImage makeintensity( lights/shadows/Example_Pre_Existing_Falloff.

tga )
 {
 blend gl_zero, gl_one_minus_src_color
 map lights/shadows/shadow_circle_01
 zeroclamp
 //alphazeroclamp
 colored
 } 
}
