This entity is obsolete. Its use is discouraged. It may only exist/function in older engine branches.
It has since been deprecated by: func_water_analog. Non-moving water brushes should be part of worldspawn.

func_water is a brush entity available in all 
Source games. Legacy entity from the 
GoldSrc engine, deprecated by func_water_analog. It is still used in some 
Half-Life: Source maps.
Important:Does not work with the Water shader.Refract can be used as a workaround for dynamic refraction with cubemapped reflections, although Valve does not provide any materials which do this.
Existing materials which are compatible include:
nature/water_movingplane.vmt(LightmappedGeneric)nature/water_dx70.vmt(LightmappedGeneric)nature/hazard_liquid.vmt(LightmappedGeneric) (only in
)liquids/!greenslime.vmt(UnlitTwoTexture) (only in 
)
Confirm:Does the Water shader work if using cubemap reflections and refractions, instead of the real-time versions? This would still be beneficial for the ability to have two normal maps scrolling in different directions.
Bug:This entity always has its contents set to CONTENTS_WATER (regardless of brush contents), with no way of setting its contents to CONTENTS_SLIME. In most games, this will only affect splash particles.
Code Fix:Add a KV that is read by CBaseDoor::CreateVPhysics to set fluid.contents (defaulting to CONTENTS_WATER if KV is absent)Code:Both func_water and func_door are linked to CBaseDoor C++ class. The game code checks the classname KV to distinguish between them, applying specific behaviors if the classname is "func_water". As such, using AddOutput to change the classname of a func_water may have unexpected effects.
Note:All Keyvalues / Inputs / Outputs are same as func_door.
