Used on Trigger and func_viscluster entities. (A Block LOS func_brush can still be traversed in this state.)Ĭasts shadows artificially. This can be worked around through turning the Block LOS textured brush into a func_brush with its Solidity keyvalue set to a solid state. Mat_wireframe 1/2 will reveal that while this texture doesn't block visleaves, it draws crossing polygons, and them alone are capable of preventing the engine from rendering enveloped brushwork. Not available in all branches.īlocks the line of sight of NPCs and bots. When placed outside of a brush entity, the compiler will fail with the error origin brushes not allowed in world. It is still functional in Source (overriding the entity's origin keyvalue), but no longer necessary. Leftover from GoldSource, where a brush with this texture was used to set the rotation origin of rotating entities. This means faces that are outside the map and faces that are flush with another one. Note: Despite common misconception, it is not necessary to use nodraw on faces that don't touch visleaves, as these are automatically removed by VBSP. Survivors stop being dragged towards smokers when touching a tools/invisible wall. Smokers, Boomers and Spitters can attack you through it. Solid to prop_physics, projectiles, players, npcs.

To allow NPCs and their line of sight to pass through, turn the brush into a func_brush with its Solidity keyvalue set to a solid state.

Projectiles from NPCs such as the acid spit from antlion workers, will still get through.

It does not block all projectiles, though. Identical to Tools/ToolsBlack texture only in white.įoremost solid to bullets, but also to NPCs and physics projectiles. In which case you may want to use vgui/black instead, or make your own tool texture. While at least in L4D2 the different shader has no impact, it might be possible that it does have a different function in other games. It cannot be lit by any type of light, but is affected by fog color.Īn example of its use is in the 'space' backgrounds during the G-Man monologues in Half-Life 2, or crude buildings in the 3D Skybox. This texture is often used for brushes that are far away and they are dark. Note: This is the Tools/ToolsBlack texture, not the Halflife/Black texture.
