$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).

If values are used in $specmap_mode that were not thought out for use - surface will get fullbright and you'll get message in the console:
