Dynamic Lighting woes

(Kaziganthe) #1

Basically, when I try to load a map that I have put some dynamic lighting in, I get an odd message about the shader that q3map2 generates.

Shader:

textures/andromeda_lights/u_lamp4_or_flicker
{
qer_editorimage textures/andromeda_lights/u_lamp4_or.tga
q3map_lightimage textures/andromeda_lights/u_lamp4_or.blend.tga
q3map_surfacelight 5000
surfaceparm nomarks
q3map_lightstyle 1
{
map $lightmap
rgbGen wave noise 0.75 0.25 0 10
}
q3map_stylemarker
{
map textures/andromeda_lights/u_lamp4_or.tga
blendFunc GL_DST_COLOR GL_ZERO
rgbGen identity
}
{
map textures/andromeda_lights/u_lamp4_or.blend.tga
blendfunc GL_ONE GL_ONE
rgbGen wave noise 0.75 0.25 0 10
}
}

Error Message:

}

{
	map textures/andromeda_trim/u_trm64_2.tga

}

I was hoping that someone might be able to enlighten me on what’s going on here…

I didn`t know that rgbGen wave could then use noise, are you sure that is a valid waveform?

it`s not in the gtk 1.2.13 manual, but if it is valid, are there any other waveforms not listed in the manual that we can use?

the vaild ones I know of are…

Sin
Triangle
Square
Sawtooth
Inversesawtooth

This is where I found and copied the value from. I’m sure that if ID made a shader with it in there, then it is valid. :cool:

EDIT: I also tried dynamic lighting in a test map, that had essentially the same shader, just different textures.

understood and thanx :slight_smile:

good luck in getting the dynamic lighting working.

Also, in case you’re wondering, I’m using the latest Q3map2.

alphaGen noise isn’t supported in Quake 3, oddly enough.

It works in ET tho… :slight_smile:

Well that’s no good :frowning: … What sort of value would give me about the same effect?

(ratty redemption) #8

you could use…

rgbGen wave triangle 0.75 0.25 0 10

in one shader stage and then in a duplicate stage, change the phase value and frequency…

rgbGen wave triangle 0.75 0.25 0.3 13

that should produce a random type flickering effect, and if you tweak the last two values you might get something similar to what you were after with noise.

(ydnar) #9

rgbGen noise will be sufficient. If you want to further modulate it on a fixed frequency, use an alphaGen with one of the wave funcs.

Forgive me for my ignorence, but are you saying that rgbGen wave noise will work in the worldspawn, but alphaGen wave noise will not? If so, then I could just keep the shader as is, and just get rid of the alphaGen value in worldspawn. Correct? :bash:

(ratty redemption) #11

also is it wave noise or just noise after the rgbgen or alphagen keywords?
