problem with custom shader

(noisyb) #1

i want a shader that does just make a red surface

textures/test/red
{
{
map $whiteimage
rgbGen const ( 1.0 0.0 0.0 )
blendFunc add
}
{
map $lightmap
rgbGen identity
blendFunc filter
}
}

…but why is it transparent?

Can anyone help? or point me to a place where someone can help? I have
had a look at the Q3A shader manual… but this is the best I can come up
with after having read it…

Blendfunc really “blends” as the name says.

I would take out the “blendFunc add” to make the shader solid.

well… it HAS to blend something… the framebuffer is transparent…

  1. i take a white texture add the color to it…

  2. i put that on the framebuffer… but the transparency is still there… i want to know how i can make the transparency in the framebuffer f*** off…

using no blend function results in solid white “textures”…

Just trust us and take out the blendFunc add in the first stage.

The framebuffer will render the whiteImage, colour it red, then blend the lightmap on top.

Actually, in hindsight, why don’t you just make things super easy and just get rid of the first stage? It’s not doing anything in the first place.


textures/test/red
{
	qer_editorImage textures/test/red.tga
	{
		map $lightmap
		rgbGen const ( 1 0 0 )
	}
}
