how to make holograms.

i wont holograms on each room doors as a sine.

But i wont make them as they make sort of sparking like going off a sec and on

hope you understand.

Don't use "hologram", as it is borked. Just use distort and set the rendering mode to additive, and set the desired level of transparency with fxamount.

what is disort ? i need to make func_illusionary ? then adative yes ?

yup

Edit: Distort is the well, what it sounds like. It makes it sort of jump around and look all hologram-y. The hologram setting itself is supposed to do this and make the object glow, as if it was emitting light (If I recall correctly, that is.) however, it was never fully implemented properly in the engine (I guess) so it never worked.
