shader problems

[Tinny]

hey guys, I'm having difficulty with a shader i'm making for a projectile. Its normally transparent but whenever its behind a wall it shows up solid, when its not even supposed to show up. Also when you shoot it into the sky or onto a burn mark or something it doesn't even show up. Anyone know what's causing it? Here's the shader file.

 

 

d3

qer_editorimage gfx/menus/planets/cos28

cull twosided

{

map gfx/menus/planets/cos28

alphaFunc GE192

blendFunc GL_ONE GL_ZERO

depthFunc disable

glow

rgbGen identity

tcGen base

tcMod entityTranslate

}
