.Map :: MoHAA Mapping

I have edited an original texture like this:

The only thing I want to know is, what must I add to my custom shader for this texture, to let the black color disappear in the game? So you can look through it you know.

Thank you,

You need to make an alpha channel to the texture in which the opaque part is white and the transparent part is black. The shader should say s/th like this:

Code: Select all

textures/mytextures/mytexture
{
  cull none // if you want it two-sided
  qer_editorimage textures/mytextures/mytexture.tga
  surfaceparm wood
  {
    map textures/mytextures/mytexture.tga
    blendfunc blend
    alphafunc GT0
    depthwrite
  }
  {
    map $lightmap
    blendfunc filter
    depthfunc equal
  }
}

g/l

thats all that goes into a shader file? name it after the texture and put it in a textures folder and that's it? that's all you have to do? awesome! (obviously change values as wanted...)

lol lizard seems to be in state of shock!

window shaders tend to be a bit longer, but most of them are about that size.

oh you might want keywords too. depending on your mapping style.

well ya i expected something much more complex... i have a coupel textures in the works and if that's all i need to do....

yea.. its simple, I use tons of custom textures(taken mostly from image packs that I add shaders to)

just put em in your pk3 in scripts labeled mapname(or whatever).shader and the textures themselves in texture/mapname(or again whatever)

for instance, I always use the mapname or working map name... and all the contruction shaders go together in one shader... in this case -

scripts/gefangenshaft.shader
textures/gefangenshaft/

Code: Select all

textures/gefangenschaft/wall_concrete_pattern2
{
	qer_keyword stone		
	qer_keyword wall
	surfaceparm stone
	{
		map textures/gefangenschaft/wall_concrete_pattern2.jpg
		depthWrite
		rgbGen identity
	}
	{
		map $lightmap
		rgbGen identity
		blendFunc GL_DST_COLOR GL_ZERO
		depthFunc equal
	}
}
textures/gefangenschaft/floor_bunker_pattern1
{
	//Origin - ?
	qer_keyword stone
	qer_keyword floor
	surfaceparm stone
	{
		map textures/gefangenschaft/floor_bunker_pattern1.jpg
		depthWrite
		rgbGen identity
	}
	{
		map $lightmap
		rgbGen identity
		blendFunc GL_DST_COLOR GL_ZERO
		depthFunc equal
	}
}
textures/gefangenschaft/wall_plaster_pattern6
{
	qer_keyword stone
	qer_keyword wall
	surfaceparm stone
	{
		map textures/gefangenschaft/wall_plaster_pattern6.jpg
		depthWrite
		rgbGen identity
	}
	{
		map $lightmap
		rgbGen identity
		blendFunc GL_DST_COLOR GL_ZERO
		depthFunc equal
	}
}

those are the last 4 entries, the keyworkds jsut make it more searchable(i only include them cause sometimes I like to see them in the same tex window with other textures of a similar type, usualy I wont be searching ot find my own custom texture.)

beware of using overly simple .shader names!

so you make texture packs by grouping multiple shaders together under a common name... awesome. i've wanted to learn this for a while now, jsut never remember to ask etc...

danke!

i dont make textures and i knew that

.i got a tutorial on q3 shaders if u want it

. making shaders is too complicated for me

Posted: **Mon Aug 02, 2004 10:14 pm**

i think i'll actually try to make something before i crack open the full q3 thingie, thanks anyway...
