Confirm:Is this full list of entities ?
Warning: This shader is pretty expensive for GPU. May not cause FPS drops, but it will heat up your GPU very much. Use wisely.
Bug:Doesn't work with VertexLitGeneric if $phong is enabled.
Bug:If alpha tested material has a specular, and beneath it, there is also a material with the same shader, and in combination with new lights or a flashlight, this all will cause artifacts appear. This occurred after Crowbar Collective fixed the outline artifacts for alpha tested materials. Example.
Note:env_cascade_light doesn't work with this shader (at least on bmodels and world geometry ).

This article or section needs to be cleaned up to conform to a higher standard of quality because:

For help, see the VDC Editing Help and Wikipedia cleanup process. Also, remember to check for any notes left by the tagger at this article's talk page.$specmap_texture is a material shader parameter available in 
Black Mesa.
This shader is used for surfaces to give PBR style shiny speculars. Works with VertexLitGeneric and LightmappedGeneric. This shader work only with deferred rendering lighting entities which support and use SpecularMultiplier parametr (in the game code or as kayvalue), the entities is: NewLight_Point, NewLight_Spot, npc_zombie_hev (flashlight), prop_barrel_cactus, prop_barrel_cactus_semilarge, prop_barrel_interloper, prop_barrel_interloper_small, env_cascade_light, bmortar, npc_plantlight, npc_plantlight_stalker, player (flashlight).
