Glass Lights VMT
Hey, I'm just trying to get something working for my Portal mod, similar to the glass_lightcover models in Portal 2. (I'm aware that using the model and textures from Portal 2 isn't allowed - I'm using my own textures and models and such, I'm just trying to imitate the effect to get a bit more depth).
Basically, I am trying to do the strange fake depth effect that the glass lights have. The closest I've gotten is refraction of the material (like the basetexture is a crosshair, its fixed to fill the view of the player and only visible through the glass).
It doesn't really seem to work in Portal 2 either (the map usually crashes).
Any help here? :c
I;m afraid I don't quite folow:
You want glass in portal 1, on a model.
You need a texture for this (thus a vmt file)
You copied properties from the portal 2 vmt's and copied them over but it does not work?
Then there is something with fake depth? What do you mean? can you give an example? possibly from p2?
I can't get a screenshot at a little bit, but you know the long glass lights? They are actually totally 2D with some fancy manipulation of textures.
I have a feeling that it is due to a shader var that i've never seen before.
The likes of "$localrefract 1".

Well the inset light models are 2d planes; ie flat. The inside refraction fakes depth because of how the internally refracted portion moves. This is a new shader effect (hence "$localrefract 1") that is non-existant in p1. @OP, you'll have to do it the way the P2 Collab did it: observation glass texture in front of a brush-built light shape behind it.
As for why it fails in p2: in p2 refacts have to be on a model.
EDIT: I did it from my ancient p2-in-p1 mappack:
Yeah, that's how i've done the lights up until now, so i guess i'll just keep doing them like that. Thankies
