Black light shader...

adam

Hey,

Has anyone ever seen a black light shader in a game before? No idea why, but the thought just hit me.

Seems possible,
It'd require a black light color texture, and a light that just effects that texture, could be a fun mini challenge.

Uly, cool.

More please.

Alan Wake uses something like it for their hidden supply crates

Not really a blacklight as such but a UV-light kinda effect.

Goddamit Adam now you have me messing around in UDK :P Have some ideas running in my head will test when I get chance from work.

In UDK, hmmmm
I'm thinking something like a light with a special channel enabled? Then decals, that are set to this lighting channel only? Doesn't seem that hard now that I think of it.

Doom3 has a similar system called light-spectrums.

Damn, that's a lot of sperm stains.

Penumbra: Overture features a room with a black light.

Does detective mode in Batman: Arkham Asylum count?

Setting a lights intensity to a negative value will give you 'blacklight.' Or am i missing the point?

Edit. Ahhh...see what you mean now. Ignore my original post.

For a surfers like me, who would come here for the answers to the question of how to make a blacklight-reacting shader.
Googling with keywords "fluorescence", "blacklight" or "UV" did't give much.
But this thing is also known as "hide reveal shader"
I would just leave it here:
It's for Unity.
There's also a github link under a video.
