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). It accepts only the most rudimentary of VMT commands.
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.
- Allow the player's flashlight to illuminate the material.
- Possibly is used to allow shadows to form from this decal. For example, found in L4D2 decals/detail/ruraldetailsprites.vmt To do: confirm.
