Decal Shader
2004-06-08, 2:27 PM #1
I'm trying to make a new decal-type shader. I saved a new .shader file with this text:
Code: 
textures/castle/symbol
{
	qer_editorimage	textures/castle/rad_seal
	polygonOffset
	q3map_nolightmap
    {
        map textures/castle/seal
        alphaFunc GE128
        blendFunc GL_DST_COLOR GL_SRC_COLOR
    }
}

The image I want to project is a grey-on-black .jpg file (textures/castle/seal.jpg). The image in Radiant is the same thing in different colors-textures/castle/rad_seal.jpg).

What am I doing wrong?

Dunno. Maybe the .jpeg needs to be a .tga

I can only echo Echoman in this matter. Try with a tga. I have one decal working fine with alpha mapped tga. My blend function for it is GL_SRC_ALPHA GL_ONE, though. I have a _glowe stage with a jpeg similar to yours: with a black bacground and blending option GL_ONE GL_ONE.

Works fine. But then again, I know very little about these things, even if I use them a lot! [http://forums.massassi.net/html/smile.gif] I just mess around changing little things as long as it takes, or I ask Gothix. Gothix always knows.

That sounds about right-in ShaderEd, I get a "Bad Filetype" message. How can I convert that .jpg to a .tga? (I'm using Fireworks 3 BTW)

I don't know what is Fireworks, but if it can handle alpha channels, then you can do it. Alpha channel is just like an 8 bit layer that defines which parts of the image are transparent and how much. So, if Fireworks can handle an alpha channel and save as tga you are fine, if it can handle transparencies and save as png, you are fine, as well.

I don't know how to modify or create png transparencies, which is the reason I use tgas.

I don't use ShaderED. Hmm. I use notepad.

I edited the shader in Notepad, then I used ShaderEd to see if it worked.

If you use an alphaFunc, you need an alphachannel. Since you don't, nuke the alphaFunc and replace GL_DST_COLOR GL_SRC_COLOR with GL_ONE GL_ONE. No longer need for a TGA that way, as well.

notepad works best.. and you dont need to make a tga file, sometimes the jpg files over-write tga files.. and all of your jpg files become one big tga shader file.. So in short, if you shader jpg files, they become a tga file on thier own.. Thats if you put tga on your textures as opposed to jpg. Still include all files in the pk3 thou.. and make sure your shaderlist has the shader you made in there.

The JA engine searches inb JPG -> PNG -> TGA order, to be exact.

Absolutely not.

Just the ones you actually use will do fine. To sort out which ones you need; use a clean version of JA, see what's missing (open the console), do a condump and add the required files to your pk3.

That.. actually made sense. *twitch*

Same solution applies.
