Noob Alpha Shader Question

So I have a texture that is alpha textured and in .tga format, now what parameters and such do I use? Its for a gate by the way... I know how to do this with .md3's, but not just plain textures for Gtk geometry

You want it to blend the outside of the texture?
Like... The black part around the gate?

Yea haha, sorry i didnt quite clarify
i know to use alphaFunc GE128 or something... other than that im not quite sure how to write it properly. Could i get an example shader from somewhere maybe?

textures/ut4_sewers/decal_radioactivity
{
qer_editorimage textures/ut4_sewers/radioactivity.tga
polygonOffset
nomipmaps
nopicmip
surfaceparm trans
{
map textures/ut4_sewers/radioactivity.tga
blendfunc filter
}
}
from cmm shader generator

It's so wrong
Use something like this:
Code: Select all
textures/coldwar/vv_et_mesh
{
qer_editorimage textures/coldwar/vv_et_mesh.tga
qer_alphafunc greater 0.5
// surfaceparm alphashadow
surfaceparm trans
cull disable
nomipmaps
surfaceparm playerclip
surfaceParm nolightmap
surfaceParm noimpact
{
map textures/coldwar/vv_et_mesh.tga
alphaFunc GE128
rgbGen vertex
}
{
map $lightmap
rgbGen identity
blendFunc GL_DST_COLOR GL_ZERO
depthFunc equal
}
}

You're the man ValkoVer thanks much
I'll have screens up of what im working on with that sometime soon
Edit- I updated my Pre-Alpha topic concerning my map, has the gate in a video and thanks to you in the decription
