UnlitGeneric draws an albedo without standard lighting passes. It is used for things like UI images, pure white, and pitch blackness, but also in situations when software lighting is used (like on detail props).
Supported Parameters
Basics
[[$basetexture|$basetexture]]
[[$surfaceprop|$surfaceprop]]
[[$model|$model]]
Adjustment
Transparency
[[$alpha|$alpha]]
[[$alphatest|$alphatest]]
[[$nocull|$nocull]]
[[$translucent|$translucent]]
Texture Organization
[[%keywords|%keywords]]
[[%notooltexture|%notooltexture]]
[[%tooltexture|%tooltexture]]
Effect
Additional Parameters
[[$receiveflashlight|$receiveflashlight]]
[[$singlepassflashlight|$singlepassflashlight]]
Caveats
Projected Texture Bugs
If a Skybox has an UnlitGeneric shader applied to it, some visual bugs can occur. Notably, if a projected texture is shone near a Skybox using an UnlitGeneric shader, the Skybox will appear to ignore surrounding geometry and phase through walls for as long as the projected texture is active.
To fix this, ensure that a sky_camera exists in the world, typically in its own box which exists outside of the rest of the map.
Preferably, use the purpose-built Sky shader instead.
Models
If this shader is being used on a model, you must specify $model 1 to prevent errors.
Mapbase
Unlit materials in Mapbase should have the shader SDK_UnlitGeneric.
