env_model is a model entity available in Day of Defeat, Cry of Fear, Paranoia, and Spirit of Half-Life.

It is used to place a model (usually an MDL) on a map, with optional animation and no collision. In the official FGD file it is descibed as a "new alternative to cyclers".

Important:Env_models do not have any collision, and will not cast shadows with normal compilers.

Workaround:A few options:

• Create a brush-based collision mesh and tie it to a func_wall with renderamt set to 0 (aka invisible) ZHLT light flags to "Opaque", and zhlt_striprad set to 1 (aka enabled). This will also cast lightmap shadows, unless alphatest ({) textures are used.
  Note:Will use up an extra edict; use sparingly.
• Use NULL brushes on a func_detail, and ensure the env_model's origin is not inside of the brushes.
• Use clip brushes. Note that clip brushes can be shot through, so this should only be done for certain niche situations. Additionally, this method will not cast lightmap shadows.
  Note:NULL and clip brushes will use the default footstep sounds when stepped on; the func_wall method should be used for non-concrete surfaces, such as tanks or sandbags.

Key Values

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Note:In Day of Defeat, unnamed env_models are made client-only after spawning. This means they only count as an edict for a split second upon loading the map or restarting the round.

Pitch Yaw Roll (Y Z X) (angles) <QAngle>

This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.

Model (model) <model path>

Model to display (MDL, BSP, or SPR). Relative to mod folder.

Colormap (colormap) <integer>

Works like the deathmatch recolor system, wherein this KV equals (bottomcolor * 256) + topcolor. This value can be calculated using .

Skin (skin) <integer> (not in )

Display different skins of the model if available.

Body (body) <integer>

Display different sub-models of the model if available.

Sequence when on (m_iszSequence_On) <string>

Displays the animation sequence of the model when on.

Behaviour when on (m_iAction_On) <choices>

Behaviour of the model when on.

Value	Description
0	Freeze when sequence ends
1	Loop
2	Change state when sequence ends

Sequence when off (m_iszSequence_Off) <string>

Displays the animation sequence of the model when off.

Behaviour when off (m_iAction_Off) <choices>

Behaviour of the model when off.

Value	Description
0	Freeze when sequence ends
1	Loop
2	Change state when sequence ends

Render FX (renderfx) <choices>

Render FX mode to use, for special effects.

Value	Description
0	Normal
1	Slow Pulse
2	Fast Pulse
3	Slow Wide Pulse
4	Fast Wide Pulse
5	Slow Fade Away
6	Fast Fade Away
7	Slow Become Solid
8	Fast Become Solid
9	Slow Strobe
10	Fast Strobe
11	Faster Strobe
12	Slow Flicker
13	Fast Flicker
14	Constant Glow
15	Distort
16	Hologram (Distort + fade)

Render Mode (rendermode) <choices>

Render Mode to use.

Value	Description
0	Normal
1	Color
2	Texture
3	Glow
4	Solid
5	Additive

Render Amount (0-255) (renderamt) <integer>

Controls transparency when using another render mode then normal. 0 is completely invisible, and 255 is opaque. If render mode is solid, then all values except 0 are opaque.

Render Color (R G B) (rendercolor) <color255>

Color to use by the specified render mode.
Also used on brush entities to control the speed of scrolling textures; see func_conveyor for more information.

ZHLT:

Copy lighting from (VHLT+) (zhlt_copylight) <targetname>

Copies the lighting from the named entity to the nearest lightmap luxel below this entity's origin.

Tip:To avoid having the copied lighting visibly affecting the brush lighting, put a 16x16x1 func_detail with zhlt_noclip enabled directly below this model's origin. Texture the top face with black_HIDDEN, and the rest of the faces with SKIP.

Note:Not compatible with entities using the effect flag EF_INVLIGHT.

Model shadows (UMHLT, SDHLT) (zhlt_studioshadow) <boolean>

Enable to cast shadows from MDLs found in the model KV.

Model shadow mode (SDHLT) (zhlt_shadowmode) <choices>

0 - Use Bounding Box

1 - Use triangles (default)

2 - Use Bounding boxes of triangles

Flags

Initially Off : [1]

Drop to Floor : [2]
