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>

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

Flags

1 - EF_BONEMERGE

Merges bones of names shared with a parent entity to the position and direction of the parent's.

Note:Does not function with the "effects" keyvalue.

2 - EF_BRIGHTLIGHT

Emits a dynamic light of RGB(250,250,250) and a random radius of 400 to 431 from the origin.

4 - EF_DIMLIGHT

Emits a dynamic light of RGB(100,100,100) and a random radius of 200 to 231 from the origin.

8 - EF_NOINTERP

Don't interpolate on the next frame.

Warning:Causes crashes.

16 - EF_NOSHADOW

Don't cast a shadow.

Todo: Does this also apply to shadow maps?

32 - EF_NODRAW

Entity is completely ignored by the client. Can cause prediction errors if a player proceeds to collide with it on the server.

64 - EF_NORECEIVESHADOW

Don't receive dynamic shadows.

128 - EF_BONEMERGE_FASTCULL

For use with EF_BONEMERGE. 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.

Note:Does not function with the "effects" keyvalue.

256 - EF_ITEM_BLINK

Blink an item so that the user notices it. Added for original Xbox, and really not very subtle.

512 - EF_PARENT_ANIMATES

Assume that the parent entity is always animating. Causes it to realign every frame.

Note:Does not function with the "effects" keyvalue.

1024 - EF_MARKED_FOR_FAST_REFLECTION

Todo: What does this do?

2048 - EF_NOSHADOWDEPTH

Todo: What does this do?

4096 - EF_NOFLASHLIGHT

Entity will not be brightened by projected textures or player flashlights.
