View source for Brush entity/Rendering related keyvalues and inputs

{{LanguageBar}}{{src topicon}}
{{toc-right}}

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]] ==
{{KV|[[Minlight|Minimum Light Level]]|intn=_minlight|normal|Minimum amount of light to hit this brush (monochromatic). Values over 1 are overbright, and will bloom in [[HDR]] mode.}}
{{KV|Cast Lightmap Shadows|intn=vrad_brush_cast_shadows|boolean|Determines if this entity will cast [[lightmap]] shadows.|since={{src07}}}}

== Keyvalues ==
{{KV Rendermode}}
{{KV Render FX}}
{{KV|Render Amount / Transparency (0–255)|intn=renderamt|int 0-255|Transparency amount; requires a Render Mode other than '''Normal'''. 0 is invisible, 255 is fully visible.}}
{{KV|Render Color (R G B)|intn=rendercolor|color255|Color tint.}}
{{KV|Texture Frame|intn=texframeindex|int|nofgd=1|The frame number for any animated textures on this entity.}}
{{KV Shadow}}
{{KV SystemLevelChoice}}
{{KV DXLevelChoice}}
{{KV Reflection}}
{{KV|Texture Frame|intn=texframeindex|int|The initial frame number for all animated textures on this entity.|nofgd=1|not={{portal2}}}}

== Inputs ==
{{IO|Alpha|param=int 0-255|Sets the entity's transparency (<code>renderamt</code>) to a number from 0 (invisible) to 255 (fully visible). Requires the entity to have its '''[[Render Mode]] (<code>rendermode</code>)''' set to a number other than <code>0</code>.}}
{{IO|AlternativeSorting|param=bool|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.}}
{{IO|Color|param=color255|Sets an RGB color for the entity.}}
{{IO|EnableDraw|since=P2|Removes {{ent|EF_NODRAW}} from the entity.}}
{{IO|DisableDraw|since=P2|Applies {{ent|EF_NODRAW}} to the entity. Note that this is different from {{ent|rendermode|10}}.}}
{{IO|EnableReceivingFlashlight|since=P2|Makes it so that the entity is lit by {{ent|env_projectedtexture}}s.}}
{{IO|DisableReceivingFlashlight|since=P2|Prevents the entity from being lit by {{ent|env_projectedtexture}}s. The shadow made by the texture will still cast.}}
{{I Reflection}}
{{I Shadow}}
