FX ammount : 255

flags: not solid

That's the entity in question. Set up exactly the same as I would in HL1.
I have a custom texture, mostly black with some white/green text on it. I want the black to be transparent, as an additive did in HL1... However, when i compile, the black is fully opaque. What gives?

You need to set it to a lower value, 255 still renders black.

Have you tried this in your .vmt?

$translucent "1"
You can also use an alpha channel to determine what will be translucent on the material.

Solokiller : that just makes it act as if i had selected Render Mode : Texture

Xyos, does the translucent property automatically make black parts translucent? I'm just wondering since you said "also" use an alpha channel.

Alpha channels mask the textures automatically. Black parts will be fully translucent, while white is fully opaque. (or the other way around, I'm not sure)

I forgot I did this before I could of told u sooner:

Here is an example for a texture that has some translucent parts, and some not translucent:

"LightmappedGeneric"

{
"$translucent" 1
"$basetexture" "mikematerials/metalvent"
"$surfaceprop" "metal"

}

In the base texture's alpha channel, create a black and white version of the material. Black is see-through, white is not. Inbetween is semi-you get the picture.

np

ooh, just a little confirmation needed.
"$surfaceprop" "metal"
that makes the bullet impact a metal decal, right? and the footstep noise etc?

Correct.
You can find the complete surfaceprop list in places like here
