View source for Effect flags

For configuring client-side visual effects.

== Usage from Hammer ==

Effect flags can be configured from Hammer. To do so turn off [[SmartEdit]] and add a new keyvalue pair:

 effects <n>

'<code>n</code>' is the sum total of the flags you want to use. For example, 66 would mean <code>EF_BRIGHTLIGHT</code> and <code>EF_NORECEIVESHADOW</code>.

== Flags ==

;1 - <code>[[EF_BONEMERGE]]</code>
:Merges bones of names shared with a parent entity to the position and direction of the parent's.
;2 - <code>[[EF_BRIGHTLIGHT]]</code>
:Emits a dynamic light of RGB(250,250,250) and a random radius of 400 to 431 from the origin.
;4 - <code>[[EF_DIMLIGHT]]</code>
:Emits a dynamic light of RGB(100,100,100) and a random radius of 200 to 231 from the origin.
;8 - <code>EF_NOINTERP</code>
:Don't [[interpolation|interpolate]] on the next frame.
{{warning|Causes crashes.}}
;16 - <code>[[EF_NOSHADOW]]</code>
:Don't create a render-to-texture shadow, does not affect projected texture shadows.
{{note|Same as disableshadows 1.}}
;32 - <code>[[EF_NODRAW]]</code>
:Entity is completely ignored by the client, and stops drawing the entity. Can cause prediction errors if a player proceeds to collide with it on the server, use <code>rendermode 10</code> instead if this is a problem.
;64 - <code>EF_NORECEIVESHADOW	</code>
:Don't receive dynamic shadows.
{{note|Same as disablereceiveshadows 1.}}
;128 - <code>[[EF_BONEMERGE_FASTCULL]]</code>
:For use with <code>[[EF_BONEMERGE]]</code>. If set, the entity will use its parent's origin to calculate whether it is visible; if not set, it will set up parent's bones every frame even if the parent is not in the [[PVS]].
;256 - <code>[[EF_ITEM_BLINK]]</code>
:Blink an item so that the user notices it. Added for original Xbox, and really not subtle.
;512 - <code>[[EF_PARENT_ANIMATES]]</code>
:Assume that the [[parent]] entity is always animating. Causes it to realign every frame.
{{Note|Does not function with the "effects" keyvalue.}}
;1024 - <code>EF_MARKED_FOR_FAST_REFLECTION</code>
:Marks the entity to render in fast water reflections.
{{note|Same as drawinfastreflection 1.}}
;2048 - <code>EF_NOSHADOWDEPTH</code>
: Stops [[env_cascade_lighting]] and [[env_projected_texture]] from making shadows for this entity.
{{note|Same as disableshadowdepth 1.}}
;4096 - <code>EF_SHADOWDEPTH_NOCACHE</code>
: Don't cache this entity into shadow depthmaps, update it every frame.
;8192 - <code>EF_NOFLASHLIGHT</code>
:Stops projected textures from making shadows for this entity.
{{note|Same as disableflashlight 1.}}
;{{CSGO add | 16384 - <code>EF_NOCSM</code>}}
:Don't cast shadows from cascade shadow maps.
