Line from button to door??
In portal they have the lines, that light up (change color), from the button to the corresponding door.
And then the x or check. (depending on door/button status).
You all know what im talking about. Anyway how do you do that!?
I already have the button, ambient generic, door, filter, basicly everything involving opening the door and animating the button so it already WORKS i just want it to look kooler.
Anyone know how??
Ps this is my first post so... Hi im zac. 
Welcome to TWP forums.
The thing you are talking about is done using an entity which changes texture index on the overlays. Can't remember its name, though... it's probably func_something
(percentage calculation sphere self-test failed!)
108.1% done, -8.1% remaining...

Nah, func_something has no values in Source. You want env_texturetoggle as your entity to change the colors of the indicators and checkmark box. Name them the same thing. Have the indicator and Checkbox named "Yummycookies" or something (Only as a test, does not have to be "Yummycookies".) The text should go bold and you set the target brushes to "Yummycookies". Then you just make the button or a switch toggle the env_texturetoggle (Which you have to name aswell.)
The more you give, the less appreciated it will be received.
Yeah, this is it 
I am off mapping for too long

Thanks guys. One more thing. Can someone list the textures please they are impossible to find. I have loads of textures showing up.
Concrete: materials/concrete/concrete_modular_ceiling001a.(vmt/vtf) (I don't really know which 
)
materials/concrete/concrete_modular_floor001a.(vmt/vtf)
materials/concrete/concrete_modular_wall001a.(vmt/vtf)
Metal: materials/metal_modular_floor001.(vmt/vtf)
materials/metal/metalwall048b.(vmt/vtf)
(for ceiling, it's the same as the floor)
No i mean textures for the line and checkbox.
* signage/indicator_lights/indicator_lights_wall
* signage/indicator_lights/indicator_lights_corner_wall
* signage/indicator_lights/indicator_lights_corner_floor
for the indicator lines
for the checkmark sign
Use this as a tutorial
