Brush entity/Rendering related keyvalues and inputs

Keyvalues

Internal keyvalues used 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.

Visible Brush:

Render Mode (rendermode) <byte choices>

Set a non-standard rendering mode on this entity.

Render Modes

0: Normal 1: Color 2: Texture 3: Glow 4: Solid/Alphatest 5: Additive 6: Removed, does nothing 7: Additive Fractional Frame 8: Alpha Add 9: World Space Glow 10: Don't Render

Render FX (renderfx) <byte 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.

Choices

0 : Default 1 : No cache - render every frame 2 : Cache it - render only once

Minimum / Maximum Effect Details Level (mincpulevel / maxcpulevel) <integer choices> (in all games since )

Don't render for players with Effect Details levels that exceed the minimum or maximum.

Choices

0: Default ("Low" for mincpulevel, "High" for maxcpulevel) 1: Low 2: Medium 3: High

Minimum / Maximum Shader Details Level (mingpulevel / maxgpulevel) <integer choices> (in all games since )

Don't render for players with Shader Details levels that exceed the minimum or maximum.

Choices

0: Default ("Low" for mingpulevel, "Very High" for maxgpulevel) 1: Low 2: Medium 3: High 4: Very High

Minimum / Maximum DX Level (mindxlevel / maxdxlevel) <integer choices> (removed since )

The entity will not exist if the engine is running outside the given range of DirectX Versions.

Choices

Warning:If these are used, the object may break when the user switches their DirectX settings.[missing string] 0 - Default (no bounding) 60 - DirectX 6 (!FGD for mindxlevel) 70 - DirectX 7 80 - DirectX 8 (GeForce4 Ti & FX 5000 series) 81 - DirectX 8.1 (GeForce FX 5800, 5900 & Radeon 8500/9100 and 9000/9200) 90 - DirectX 9 Shader Model 2 92 - OpenGL аналогичен DirectX 9 Shader Model 2 (using ToGL; only) !FGD 95 - DirectX 9 Shader Model 3 (in all games since ) 98 - DirectX 9 Shader Model 3 on Xbox 360 ( only) !FGD

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.

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 than 0.

AlternativeSorting <booleanRedirectInput/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 <color255RedirectInput/color32>

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 from rendermode 10.

EnableReceivingFlashlight  (in all games since )

Makes it so that the entity is lit by env_projectedtextures.

DisableReceivingFlashlight  (in all games since )

Prevents the entity from being lit by env_projectedtextures. 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.
