[SOLVED] Shiny surface of windows

[MajkiFajki]

This is question related to old discussions:

I can do what I want, but the main problem is reflection intensity. I have tried two q3map_surfacelight values:
400:


and 800:


Reflection image is this:



I tried other - even completely black image. Still heavy-reflection.


Is there something in sky shader, that is responsible for that?

I have tried two shaders:

Code: Select all

textures/ut4_poland/chmury1niebo
{
   surfaceparm noimpact
   surfaceparm nolightmap
   surfaceparm sky
   q3map_surfacelight 400
   q3map_lightRGB 255 255 255
   qer_editorimage textures/ut4_poland/chmury1niebo.jpg
    skyparms - 512 -
   {
      map textures/ut4_poland/chmury1niebo.jpg
      tcMod scale 3 3 //4 4
      tcMod scroll 0.0200 0.00200
   }
}

And:

Code: Select all

textures/ut4_poland/polniebo1
{
qer_editorimage textures/ut4_poland/polniebo1.jpg
surfaceparm noimpact
surfaceparm nolightmap
surfaceparm sky
q3map_sun 255 255 209 500 130 55
q3map_lightRGB 255 255 209
q3map_surfacelight 275
    q3map_backsplash 0 0
    skyparms - 512 -
   {
      map textures/ut4_poland/polniebo1.jpg 
      tcMod scale 3 3 //4 4
      tcMod scroll 0.0200 0.00200
   }
} 

No difference. I want to have bright, sunny day and slight reflection on windows. How can I achieve that?

rgbGen const ( 0.2 0.2 0.2) in the glass shader, more precisely in the stage that adds the reflection image.

[MajkiFajki]

shader of windows:

Code: Select all

textures/ut4_polandwindows/polokno1

{

   {   

      map textures/ut4_polandwindows/polokno1.tga

   }

   {

      map textures/ut4_polandwindows/reflet01.jpg

      tcgen environment

      blendFunc GL_ONE GL_ONE
      rgbGen const ( 0.2 0.2 0.2)
      tcMod scroll 0.0200 0.00200

   }



   {

      map textures/ut4_polandwindows/polokno1.tga

         blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA

   }

   {

      map $lightmap

      blendfunc GL_DST_COLOR GL_SRC_COLOR 

   }

}

No effects I guess...

[Rayne]

// plain white glass
textures/glass/glass7
{
qer_editorimage textures/glass/glass7.tga


qer_trans .5
cull disabled
q3map_lightmapFilterRadius 0 32
q3map_backSplash .5 -16


{
map textures/glass/glass7.tga

rgbGen identity
blendFunc filter
}
{
map textures/resident/sfx2.tga
tcgen environment

blendFunc add
rgbGen const ( 0.3 0.3 0.3 )
}


}


I think that one might work. Not sure haven't used it in a while and don't have time to test it right now. It's pretty old so it might same some bugs.

[MajkiFajki]

Still nothing

[Rayne]

// plain white glass
textures/glass/glass_Statue
{
qer_editorimage textures/glass/glass_Statue.tga


qer_trans .5

q3map_lightmapFilterRadius 0 32
q3map_backSplash .5 -16


{
map textures/glass/windows2.tga
tcgen environment
blendFunc add
rgbGen const ( 0.3 0.3 0.3 )
}


}


This is about as simple as it can be. No basic texture just an image that impersonates reflection. Clear white glass.

rgbgen const controls the opacity and color.

Try this

Code: Select all

textures/coldwar/window
{
            qer_editorimage textures/coldwar/window.jpg
   {
           map textures/coldwar/vv_env.jpg
           blendFunc GL_ONE GL_ONE
           tcgen environment
   }
   {
                    map textures/coldwar/vv_window.tga
   }
   {
           map $lightmap
                    rgbGen identity 
                    blendFunc filter
   }
}

Delirium helped me out on IRC. The correct shader is:

Code: Select all

textures/ut4_polandwindows/polokno1
{
   {   
      map textures/ut4_polandwindows/polokno1.tga
   }
   {
      map textures/ut4_polandwindows/polodbicie1.jpg
      tcgen environment
      blendFunc blend
      AlphaGen const 0.2
      tcMod scroll 0.0200 0.00200
   }

   {
      map textures/ut4_polandwindows/polokno1.tga
         blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
   }
   {
      map $lightmap
      blendfunc GL_DST_COLOR GL_SRC_COLOR 
   }
}

Two important lines are:
blendFunc blend
AlphaGen const 0.2
