Hi there!

Actually I need to brighten up the scene I am mapping. So I copied the original shader:

Code:
textures/nki_shaders/tropicalsky
{
qer_editorimage env/sky1/sky001_ft.jpg
nopicmip
noMipMaps
// q3map_lightmapFilterRadius self other
q3map_lightmapFilterRadius 0 8 //to blur q3map_skylight when it has less than 4 iterations, to avoid the "stadium effect"
// q3map_skylight amount iterations
q3map_skylight 70 4
q3map_lightRGB 0.4 0.75 1
// q3map_lightmapBrightness 2.0
// q3map_sunExt red green blue intensity degrees elevation deviance samples
q3map_sunExt 1 0.84 0.51 140 200 40 4 4
// q3map_lightsubdivide 256
q3map_globaltexture
skyParms env/sky1/sky001 512 -
surfaceparm noimpact
surfaceparm nolightmap
surfaceparm sky
}

I rised the intensity value from 140 to up tp 1200 (at q3map_sunEXT command). There was no difference in the compiled map though. I removed any point light and... darkness...

Then I used a simple skybox definition (which worked in other games):

Code:
textures/whatever/sky/pr512
{
  qer_editorimage textures/whatever/sky/pr512_up.tga
  surfaceparm noimpact
  surfaceparm nolightmap
  q3map_globaltexture
  q3map_lightsubdivide 256
  q3map_surfacelight 400
  surfaceparm sky
  q3map_sun 1.0 1.0 0.8 150 180 80
  skyParms textures/whatever/sky/pr512 128 -
}

Even this didn't work. Darkness. Any ideas?

Thanks.

EDIT: The sky itseld can be seen though.

Just for testing reasons, what tells you q3map2 during light compilestep?
Try to replace your environmental map with some clouds and see if it works.

Code:
skyParms full 512 -
{
map textures/skies/intelredclouds.jpg
tcmod scale 2 3
tcmod scroll -.01 .02
}
{
map textures/skies/killsky_1.jpg
blendfunc filter
tcmod scale 3 2
tcmod scroll 0.05 0.03
}

This is quote from light step:

Code:

Fast mode enabled
Default lightmap sample size set to 4x4 units
Adaptive supersampling enabled with 2 sample(s) per lightmap texel
Lightmap filtering enabled
Patch shadow casting enabled
Dark lightmap seams enabled
Storing all lightmaps externally
Default lightmap size set to 256 x 256 pixels
Storing all lightmaps externally
Custom info parms enabled

Loading C:\whatever.map
entering C:\whatever.map
--- SetupGrid ---

    10850 grid points
       10 point lights
        0 spotlights
        0 diffuse (area) lights
        0 sun/sky lights
       10 total lights
        0 culled lights

   694112 luxels used
        0 luxels stored (0.00 percent efficiency)
       96 solid surface lightmaps
      119 identical surface lightmaps, using 863278 luxels
        0 vertex forced surfaces
        0 vertex approximated surfaces
        8 BSP lightmaps
        8 total lightmaps
       34 unique lightmap/shader combinations

Looks okay to me. About the sky thing, I will try this later.

        0 spotlights

        0 sun/sky lights

        0 culled lights
This is not okay. (0 sun/sky lights)
q3map2 doesn't read your shader the right way or you didn't apply the sun shader to your sky brush.

Damn, you're right. Might be related to the other problem I recently posted (http://openarena.ws/board/index.php?topic=1820.0). When I fixed this I will post here. Thanks so far!

BTW: The sky shader is applied to the sky brush.
