Func reflective glass

func_reflective_glass (Note how NPC's and env effects are reflected)

Entity description

It is used to produce perfectly reflective glass that renders world + entities. You must use a LightmappedReflective texture (glass/reflectiveglass001.vmt is a good start) on one side of the brush, and the rest of the sides either nodraw or some other opaque texture for this to work properly.

Note:This entity will not show a player their own reflection, however it will render other players.

Bug:This entity will cease to render or cause visual artifacts if water and or portals are in a visible visleaf.  [todo tested in ?]

Bug:If more than one face of this brush entity contains a reflective or translucent texture, then the mirror's behavior will suddenly switch depending on one's perspective. To prevent this, make sure exactly one surface has the reflective texture. All others must be opaque.  [todo tested in ?]

Keyvalues

Solidity (Solidity) ([todo internal name (i)]) <choices>

Used to control the solidity/collision of these brushes.

• 0: Toggle - The solidity can be toggled together with its visibility.
• 1: Never Solid
• 2: Always Solid

Solid BSP (solidbsp) ([todo internal name (i)]) <boolean>

Set this to BSP if the player seems to rotate oddly relative to the surface.

• 0: VPhysics
• 1: BSP (QPhysics)

NPC class excluded from collisions (excludednpc) ([todo internal name (i)]) <classname>

If an NPC classname (i.e. npc_zombie) is specified here, NPCs of that type won't collide with these brushes.

Invert NPC class exclusion (invert_exclusion) ([todo internal name (i)]) <boolean>

If set, then the excluded NPC class will consider this brush solid, and all other NPC classes will consider it non-solid.

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

Tip:If Solidity is Toggle, disabling will also make the entity non-solid.

Inputs

SetExcluded

Change the NPC class that does not collide with the brush.

SetInvert

Whether to reverse the NPC class exclusion rule.

EnableDisable:

Enable / Disable

Enable/disable this entity from performing its task. It might also disappear from view.

SetDamageFilter <targetnameRedirectInput/string>

Sets a filter for this entity for when it receives damage.

EnableDamageForces

Allows the entity to be pushed by damage done to it (usually force amount correlates with the damage done).

DisableDamageForces

Prevents the entity from being pushed by damage done to it.

Todo: move/mention at proper place
