If I just link a texture to this I can make it a "sky" shader?

Also there is no specific `grasssteps`surface parm... is that something that needs to be coded into the engine?

Why is it not see through? lol

Transparent textures require a .shader(.shd) file AND an alpha channel. The texture format must also support alpha channels. .jpg does not. An alpha channel is a grescale image(layer) that shows the engine what part of the texture is to be solid and what part is transparent.

ah so only 32bit tgas... rgr thanks

.png also works. And i think it takes less memory with only some loss of quaility. I haven't experimented with it much.

I added a alpha channel to the texture and saved it as a tga.. still no luck :S

[Rab,d]

did you change the .shader to reflect the new extention?
Also...you have to make or update the .shd file for EGL, too.
the .shader files are only for the map making process..because that's what q3map2 recognizes....but EGL uses the .shd files. They are placed in the /baseq2/scripts folder.

Ah yes now it works thanks rabies

Portable Network Graphics (PNG play /ˈpɪŋ/[2]) is a bitmapped image format that employs lossless data compression.

FYI, you can use .jpg and the line alphagen const .5 to fake a "alpha channel" if you want it to be see through.

But what really fixed the problem was putting them both in the .shd and .shader folders.
