Title: shader stuff
Post by: swamp-cecil on December 14, 2010, 09:57:48 pm

so, i want to make a texture that is transparent on white areas on the texture and can be walked through. Here is my code. Since it is my first shader coding, it would probably be wrong.

Code: [Select]

textures/sinix/warning
{
{
map textures/sinix/warning.tga
surfaceparm trans
surfaceparm nonsolid
surfaceparm nolightmap
blendfunc add
}
}
i took the display from arachnig2 and modified it. does this work?
REMEMBER: the WHITE parts MUST be transparent, not the black parts.

surfaceparm section should be right after 'textures/sinix/warning {'
Check shader manual for details

google -> shader manual? =D
Ok,ok... i know, u lazy like we all here. Try check here: http://q3map2.everyonelookbusy.net/shader_manual/ (http://q3map2.everyonelookbusy.net/shader_manual/)
seriously... you trying mapping without shader manual knowledges? There is a lot of amazing things you can do using only shaders. Learning how shaders work take a lot of time, but totally worth it.

PS lol, my site 7th on 'shader manual' request in google! O_o

UPD: You can try shaders editor Q3ASE: http://www.bpeers.com/software/q3ase/q3asetutorial.html (http://www.bpeers.com/software/q3ase/q3asetutorial.html), but i strongly recommend read shaders manual for basic knowledges.

Looked at this (http://tremulous.net/forum/index.php?topic=14711.0) topic at all for the transparency?

Oh, try checking out Ingar's hologram textures in Vega and Procyon.

Yes it should still work.

- Make a detail brush.
- Completely texture with common/nodraw.
- Texture one brush face with your shader.


Possible configuration:

Code: [Select]

textures/sinix/warning
{
    qer_editorimage textures/sinix/warning.tga //image to display in radiant

    nomipmaps //prevents resolution decrease due to distance
    nopicmip //prevents resolution decrease due to distance

    surfaceparm trans
    surfaceparm nonsolid
    surfaceparm nolightmap
    surfaceparm nomarks

    deformVertexes autosprite2 //shader always faces the player

    {
        map textures/sinix/warning.tga
        blendfunc filter
    }
}
