models with alpha channel and fog

[Nahuel]

hello forum, i am making a map in darkplaces with some models. I add fog but i have a problem:




the fog affects the models and dissapear when i move the mouse If i do not add shader scripts this bug doesnt appear but the models looks with transparency.

I need the correct shader to do not have bugs, i use this shader and didnt work correctly

Code: Select all

   {
   map models/vegetales/pine1
   alphaFunc GT0
   rgbGen vertex
   }


I also test this taken from the multiplant pack from quake 3 arena

Code: Select all

    surfaceparm alphashadow
    cull none
    nopicmip
   {
      map models/mapobjects/multiplant/pine1
      blendFunc GL_ONE GL_ZERO
      alphaFunc GE128
      depthWrite
      rgbGen identityLighting
   }
   {
      map $lightmap
      rgbGen identity
      blendFunc GL_DST_COLOR GL_ZERO
      depthFunc equal
   }


this doesn´t work correctly i have exactly the same bugs


Any help?

If it changes depending on view direction then I'm pretty sure it's an engine bug and I'll need to run the map myself to examine renderer state.

it works fine for me
using this shader

Code: Select all

textures/tree1/tree
{
   surfaceparm alphashadow
   surfaceparm nomarks
   surfaceparm trans
   cull disable
   nopicmip
   dpmeshcollisions
   {
      map textures/tree1/tree.tga
      rgbGen identity
      depthWrite
      alphaFunc GE128
   }
   {
      map $lightmap
      blendfunc filter
      rgbGen identity
      tcGen lightmap
      depthFunc equal
   }
}


might be some useless lines in there, I forgot already, but it works fine
