Skies and light

[mikemj33]

I've been reading in a few quake 3 tutorials that the skies emit light. How do I go about doing this in JK?

 

Thanks

Certain skies do emit light. What you have to do is make a brush that is to be a sky. Then, from the skies menu under Textures, look for a sky that you like out of the component pieces, and then find the shader (it will be one of the small, blue and black checkered looking textures with a white border around it) that has a matching name. Use only the shader to make the sky. Don't worry about it saying it can't load the texture during editing or during the bsp process, it will work in the game. If you want an example of a sky that emits light, artus_light or yavin will do. Also note that both of those skies also have ground components, so you can make an entire box of nothing but sky and then place your level within it.

Ok, I'll have to try that.

 

Now since I have this thread here I'll get this one out of the way too. Is there a specific bsp that will fuly light the level, just so I can test it without setting up all the lights?

[Tigris]

try the bsp nolight. that should be it...

[mikemj33]

Thanks, I think I'm getting the hang of this now.

Thanks just the info I was looking for also.

ok guys i had the same problem, but i got a solution.

 

open the shader file for skies by pressing shift + Left-click on mouse on a sky shader file.

 

ok now when you want a certain sky to emit light (IE: i wanted the bespin one, so i'll show you what i did)

 

WHEN YOU OPEN THE SHADER FILE IT SAYS THIS:

 

textures/skies/normallight

{

qer_editorimage textures/skies/sky.tga

q3map_surfacelight 75

q3map_lightsubdivide 512

sun 0.75 0.79 1 250 0 65

surfaceparm sky

surfaceparm noimpact

surfaceparm nomarks

q3map_nolightmap

skyParms textures/skies/nebula2 512 -

}

 

textures/skies/ships

{

qer_editorimage textures/skies/sky.tga

surfaceparm sky

surfaceparm noimpact

surfaceparm nomarks

q3map_nolightmap

skyParms textures/skies/nebula2 512 -

}

 

textures/skies/bluelight

{

lightcolor ( 0 0 1 )

qer_editorimage textures/skies/sky.tga

q3map_surfacelight 35

sun 0.75 0.79 1 130 0 40

surfaceparm sky

surfaceparm noimpact

surfaceparm nomarks

q3map_nolightmap

skyParms textures/skies/nebula2 512 -

}

 

textures/skies/orangelight

{

lightcolor ( 1 0.501961 0 )

qer_editorimage textures/skies/sky.tga

q3map_surfacelight 200

q3map_lightsubdivide 512

sun 0.75 0.79 1 250 40 60

surfaceparm sky

surfaceparm noimpact

surfaceparm nomarks

q3map_nolightmap

skyParms textures/skies/nebula2 512 -

}

 

textures/skies/test

{

qer_editorimage textures/skies/sky.tga

q3map_surfacelight 75

q3map_lightsubdivide 512

sun 0.75 0.79 1 50 0 65

surfaceparm sky

surfaceparm noimpact

surfaceparm nomarks

surfaceparm metalsteps

q3map_nolightmap

skyParms textures/skies/test 512 -

}

 

textures/skies/test2

{

qer_editorimage textures/skies/sky.tga

surfaceparm sky

surfaceparm noimpact

surfaceparm nomarks

notc

q3map_nolightmap

skyParms textures/skies/desert 512 -

}

 

textures/skies/bespin

{

qer_editorimage textures/skies/sky.tga

surfaceparm sky

surfaceparm noimpact

surfaceparm nomarks

notc

q3map_nolightmap

skyParms textures/skies/bespin 512 -

}

 

 

now you see the part where it says textures/skies/bespin

you need to add some lines to the code. add the following code after on the next line where it says qer_editorimage textures/skies/sky.tga

 

q3map_surfacelight 75

q3map_lightsubdivide 512

sun 0.75 0.79 1 50 0 65

 

then take out the line that says "notc" and replace it with this line:

 

surfaceparm metalsteps

 

I did this, and my Bespin Sky admited light. i'm sure you can change the values of the sun to change how much light you want (i still need to try that out) but other then that there you go. Hope that Helps! :D

[UniKorn]

Hrm,

 

surface parm metalsteps means that if you step on it, you will hear metal steps. Why would that be needed in a sky shader?

[Pogwaffle]

It would have to be an accident. They probably took it from another texture and forgot for get rid of the metalsteps line. No matter.

[UniKorn]

Well the shaders name is test But I was actually talking about the solution that was being provided

[Locke101]

i added that line in just to make sure it would work guys. i havn't tried without it yet, but i will after i get home. I am in school right now during 2nd period. But it works trust me, i got my bespin sky to amit light. just need to see if i can make it so that not that much light is given off the shader because i want my map do be more like during the evening.

[AKPiggott]

I tried it, it didn't work. Plus wouldn't editing the shader affect all maps in the game that use that shader?

[Locke101]

which bsp command did you use?

[AKPiggott]

I used the full one, and it was the same as it was before, the sky was lit up, but it didn't light the outdoors.

[kanehart]

can can some take a picture on where you change the light settings. Where you can make one light really bright. I have seen others but did not look the same. Pls. maybe some other screens on on the steps on adding a light then making it bright.

 

here is some place you can store the pics:
