Hi all,

I have a custom skybox. I'm currently using env/xnight2.

Here is the shader:

textures/skies/xnight2_xian_dm4
{
surfaceparm noimpact
surfaceparm nolightmap
qer_editorimage textures/skies/xnight2_up.tga
q3map_sun 1 1 1 80 -41 58
q3map_surfacelight 50
skyparms env/xnight2 - -
}

What I would like to do is add a layer of clouds to the sky. Cloud texture (dimclouds.jpg)

First, I tried altering the shader, but never could get it to work.

Second, I tried adding a second layer across the sky with a cloud shader; however, it will never line-up perfectly and you see the edges.

The ideal outcome I would like to have this sky with far/high layer clouds going across the entire sky (top and sides) without seems and doing it with the sky shader.

Is this doable?

Rewrite the below to fit your needs, it has two cloud layers mapped under a environment map.
Of Course there will be seams, in the bottom of the sky. To remedy this you could skip one layer and add a alpha mask to blend the one left cloud layer with the bottom of the sky. Or you can work this in into the sky portal.

Code: Select all

textures/hipshot_m7_sky/prodm6sky
{
	qer_editorimage textures/hipshot_dm6_sky/env/dm6_up.tga
	q3map_lightmapFilterRadius 0 32
	q3map_sunExt 1 .9 .5 300 -150 60 2 32
	q3map_lightimage textures/hipshot_m7_sky/blue.jpg
	q3map_skyLight 80 6
	q3map_noFog
	q3map_globalTexture
	surfaceparm sky
	surfaceparm noimpact
	surfaceparm nolightmap
	skyparms textures/hipshot_m7_sky/far 500 -
	nopicmip
	{
		map textures/hipshot_m7_sky/clouds.tga
		tcMod scroll 0.0150 -0.0050
		tcmod scale 5 5
		blendFunc blend
		rgbGen identityLighting
	}
	{
		map textures/hipshot_m7_sky/clouds2.tga
		tcMod scroll 0.03 -0.02
		blendFunc blend
		tcmod scale 3 3
		rgbGen identityLighting
	}		
}

thanks for the info. My real issue was that I was calling the shader -
textures/skies/xnight2_xian_dm4 and since that one already exist. It was always using that one, not the one I was editing. So when I just renamed it, it worked. Bah, I'm such a noob when it comes to shaders and skyboxes.

Thanks, again.

If I only altered 1 of the 6 sides of the env, is there anyway I can just included that 1 sided in my pk3 file and use the other 5 sides from the pak1.pk3 file?

No, because the shader only references the base name of the textures. If you modify one you need to modify the name, hence you'll need to include a fresh copy of the other 5 textures, renamed to suit.

I was afraid of that, thanks.
