Env screenoverlay

env_screenoverlay in practice using effects/combine_binocoverlay

Template:Base point It can display and control a set of screen overlays, to be displayed over the player's view. Useful for view effects like drunkenness, or teleporter afterimages, etc.

Note:An overlay will be applied to all players in multiplayer games.

Materials

You can use any material as an overlay, but UnlitGeneric ones are recommended to avoid artefacting.

Valve provide these materials in the /effects folder:

combine_binocoverlay

Combine binoculars

tp_eyefx/tpeye

Green teleport shimmer

tp_eyefx/tpeye2

Red teleport shimmer

tp_eyefx/tpeye3

Blue teleport shimmer

tp_eyefx/tp_eyefx

Drugged distortion

tp_eyefx/tp_black

Black. A probable bug makes it so that a thin border around the overlay is still visible.

tp_eyefx/tp_eyefx_eli

Flashing animation of three figures. Hardly usable as an overlay.

These materials are not designed as screen overlays, but will work as one:

debug/yuv

effects/com_shield002a.vmt

The combine shield shader effect - refraction with drifting squares.

models/effects/portalfunnel_sheet
