Signage help?
I figure this has been asked already, but I'm really having trouble here.
I want to make my own indicator signs for my map. The problem is that when I use my textures in the map, they're not "bright" like the official ones are. They just look a dull grey. Can anyone help.
The above image is what I eventually made, and the below image is the effect I was trying to go for.
If I recall correctly, you have to check a ccheckbox "Texture is self-illuminated" (or something like that), when making the VTF file.
It's been some years since I was making a texture so anyone correct me 
(percentage calculation sphere self-test failed!)
108.1% done, -8.1% remaining...
Released here!
All maps for Portal (1/2) worth playing are mirrored here.
I think you can just add this line to the vmt file:
- Code: Select all
"$selfillum" 1
Portal 1: Portal Pro, Resurrection, Dyad, Rexaura
Portal 2: [Coop] Electrophobia, [PTI] EotM Collection, [SP] Aperture Halloween
Yeah just make your vmt this:
- Code: Select all
"LightmappedGeneric"
{
"$basetexture" "signage/signage_overlay_cake"
"$decal" 1
"$surfaceprop" "glass"
"$selfillum" 1
"%keywords" "portal"
}
Their textures also have an alpha channel which controls the glow, a flat 123,123,123 for the white sections and 0,0,0 for the design and frame of the overlay so the black doesn't look like it's also emitting light.

What I do for my signage is I open an original signage texture in the GIMP (the only free program I can think of that has alpha channel control), copy the alpha channel and paste in my custom signage, edit it a little, and save. Then in the vmt put selfillum.
BTW the selfillum is also used for the checkmark signs, just FYI.

I downloaded GIMP and decided to give it a shot. I used Reepblue's blank signage texture along with one of my own, and put the selfillum into the VMT fine. And...
I thought it had worked...at first. But then I walked up to it.
For whatever reason, the texture vanishes the moment I get too close. And if I try looking at it at an angle, it seems to shift out of place.
Post your entire VMT.

- Code: Select all
"LightmappedGeneric"
{
"$basetexture" "signage/signage_wolf"
"$decal" 1
"$surfaceprop" "glass"
"$selfillum" 1
"%keywords" "portal"
}
I gotta head out now, but before I go, here are the two graphics in their raw forms:
- Code: Select all
"LightmappedGeneric"
{
"$basetexture" "signage/signage_wolf"
"$decal" 1
"$surfaceprop" "glass"
"$selfillum" 1
"%keywords" "portal"
}
Remove the "$decal" 1 statement if you're using the material on a brush face. It is only needed for overlays, like the indicator strips and the signs placed on the floor.
Textures with "$decal" 1 won't render correctly on normal brushes.
Other Portal 2 maps: Medusa Glare
Portal 1 maps: Try Anything Twice | Manic Mechanic
Textures with "$decal" 1 won't render correctly on normal brushes.
Oh sweet, that worked! Thank you!
