Rendering related keyvalues and inputs
Following keyvalues and inputs are available for all brush entities and are mostly relevant only for those which are visible (possible exception would be casting shadows with not rendered brush). There may still be rendering related keyvalues and inputs available only to specific brush entities[confirm] and those would be listed on their pages.
Keyvalues read only by VRAD
- Minimum Light Level
(_minlight)
<normal> - Minimum amount of light to hit this brush (monochromatic). Values over 1 are overbright, and will bloom in HDR mode.
- Cast Lightmap Shadows
(vrad_brush_cast_shadows)
<boolean> (in all games since ) - Determines if this entity will cast lightmap shadows.
Keyvalues
- Render Mode
(rendermode)
<choices> - Set a non-standard rendering mode on this entity.
- Render FX
(renderfx)
<choices> - Various somewhat legacy alpha effects. See render effects
- Render Amount / Transparency (0–255)
(renderamt)
<integer 0–255> - Transparency amount; requires a Render Mode other than Normal. 0 is invisible, 255 is fully visible.
- Render Color (R G B)
(rendercolor)
<color255> - Color tint.
- Texture Frame
(texframeindex)
<integer> !FGD - The frame number for any animated textures on this entity.
Shadow:
- Disable Shadows
(disableshadows)
<boolean> - Prevents the entity from creating cheap render-to-texture shadows, or lightmap shadows if the entity is a prop_static. Does not affect shadow mapping.
- Disable Receiving Shadows
(disablereceiveshadows)
<boolean> - Prevent the entity from receiving dynamic shadows on itself.
- Shadow Cast Distance
(shadowcastdist)
<integer> !FGD - Sets how far the entity casts dynamic shadows. 0 means default distance from the shadow_control entity.
- Disable Shadow Depth
(disableshadowdepth)
<boolean> (in all games since ) - Used to disable rendering into shadow depth (for projected textures) for this entity.
- Disable flashlight
(disableflashlight)
<boolean> (in all games since ) - Used to disable projected texture lighting and shadows on this entity.
- Projected Texture Cache
(shadowdepthnocache)
<integer choices> (in all games since ) - Used to hint projected texture system whether it is sufficient to cache shadow volume of this entity or to force render it every frame instead.
|
- Minimum / Maximum Effect Details Level
(mincpulevel / maxcpulevel)
<choices> (in all games since ) - Don't render for players with Effect Details levels that exceed the minimum or maximum.
|
- Minimum / Maximum Shader Details Level
(mingpulevel / maxgpulevel)
<choices> (in all games since ) - Don't render for players with Shader Details levels that exceed the minimum or maximum.

See also: cpu_level / gpu_level convars
- Minimum / Maximum DX Level
(mindxlevel / maxdxlevel)
<choices> (removed since ) - The entity will not exist if the engine is running outside the given range of DirectX Versions.
Warning:
|
- Render in Fast Reflections
(drawinfastreflection)
<boolean> (in all games since ) - If enabled, this entity will render in fast water reflections (i.e. when a water material specifies
$reflectonlymarkedentities
) and in the world impostor pass. - Texture Frame
(texframeindex)
<integer> (not in ) !FGD - The initial frame number for all animated textures on this entity.
Inputs
Alpha
<integer 0–255>- Sets the entity's transparency (
renderamt
) to a number from 0 (invisible) to 255 (fully visible). Requires the entity to have its Render Mode (rendermode
) set to a number other than0
.
AlternativeSorting
<boolean>- Swaps the rendering order of the entity. Used to attempt to fix sorting problems when rendering, for example an object rendering in front of translucent materials.
Color
<color255>- Sets an RGB color for the entity.
EnableDraw
(in all games since )- Removes
EF_NODRAW
from the entity.
DisableDraw
(in all games since )- Applies
EF_NODRAW
to the entity. Note that this is different fromrendermode 10
.
EnableReceivingFlashlight
(in all games since )- Makes it so that the entity is lit by
env_projectedtexture
s.
DisableReceivingFlashlight
(in all games since )- Prevents the entity from being lit by
env_projectedtexture
s. The shadow made by the texture will still cast.
Reflection:
DisableDrawInFastReflection
(in all games since )- Turns off rendering of this entity in reflections when using
$reflectonlymarkedentities
in water material.
EnableDrawInFastReflection
(in all games since )- Turn on rendering of this entity in reflections when using
$reflectonlymarkedentities
in water material.
Shadow:
DisableShadow
- Turn dynamic shadows off for this entity. Identical to applying
EF_NOSHADOW
.
EnableShadow
- Turn dynamic shadows on for this entity.
DisableReceivingFlashlight
(in all games since )- This object will not receive light or shadows from projected textures.
EnableReceivingFlashlight
(in all games since )- This object may receive light or shadows from projected textures.
