Ok, we have tried several ways to create transparant textures for SoF II but we've had no luck.

We saved the file as a .png file.
We tried to save it as a .tga file but the editor didn't like that so it didn't work.

Point, we made the textures partially transparant, but in-game they are not transparant.
What do we need to do to let the transparancy work? Which settings do we need?

Thanks in advance,
Frank

All I done was a simple little search in this forum and came up with this. I had no luck with it so if you get it figured out let me know. lol

Alpha Texture Thread

you can do it 2 ways

PNG file: start with a transparent layer in photoshop, the transparency ingame is where you dont draw, no need for an alpha channel.

32 bit TGA: make all the transparent parts 128 grey and also create an alpha channel.

both ways need a shader for them made. i suggest to rename and use one of ravens tranparent textures to test if your problems are in the shader you made or if the problem is with your texture. with a little trial and error you will figure it out.

Ok I'm way over my head right now. How do you make this work?

This is what I have done:

1. I made a square on a transparent background in Photoshop.

2. I saved it as a 512 x 512 TGA file, Interlace none. With this as a result:


The name of this image is: test.tga

3. I've loaded the texture in Radiant and everything looked fine.

4. I created the pk3 file and the shader. I named the shader: test.shader because the name of my map is test and I've put it in my pk3 in a folder named shaders
My shader looks like this:

textures/test/test
{
surfaceparm nonsolid
surfaceparm nonopaque
surfaceparm playerclip
surfaceparm monsterclip
q3map_alphashadow
cull disable
{
map textures/test/test
alphaFunc GE128
blendFunc GL_SRC_ALPHA GL_ZERO
depthWrite
}
{
map $lightmap
blendFunc GL_ONE GL_ZERO
depthFunc equal
}
{
map textures/test/test
blendFunc GL_DST_COLOR GL_ZERO
depthFunc equal
}
}

5. I Compile the the level, create the pk3, and I start the game. And what do I see? Well this:



So what am I doing wrong? I really want this to work and I hope someone can tell me what I am doing wrong here. I will keep trying until I know how to make this textures.

Hope to hear from some,

Frank

make sure you have defined the transparent area in the alpha channel for that image in photoshop. look at your CHANNELS. you will have 3 for color (RGB) and a forth for alpha (transparency). if it doesn't exist, then create a new layer and it should end up being your alpha. whatever is black in the alpha channel will be transparent and white will be opaque.

Also, when you save as a TGA, make sure you save it as a 32bit image. 24 bit images do not contain alpha channel information.

I don't know if this is why your image is not working in the game, but it is important to know.

Use the PNG format instead of TGA and make the gray colour transparent.

What Gray colour? I have never used gray color so far....

From that test.png above

Isn't it gr"e"y? ;)

My ID was to make the white area transparent. And you only saw the quare then.

I will create such an transparent image for you in the evening when I am at home. It's easier then you might think.
