English (en)Translate (Translate)
New specular shader, example in bs_c3m0d. You can see how the floor reflects the red light source, the same for the floodlight.

This shader using for surfaces to give PBR style shiny speculars. For models this shader enables with phong shader automatically, for world geometry you're need to add some specific parameters to make it working. 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, prop_barrel_cactus, prop_barrel_cactus_semilarge, prop_barrel_interloper, prop_barrel_interloper_small, env_cascade_light.

Confirm:Is this full list of entities ?
Warning.pngWarning: This is pretty expensive shader for video cards, in large quantities may not cause optimization problems, but it will heat up your video card very much. Use wisely.

Parameters and Effects

$specmap_texture $specularcolor $specmap_mode $speculargloss

Issues

World geometry doesn't work with env_cascade_light

Unlike models - speculars doesn't work with env_cascade_light for world geometry.

Fullbright glitch with $specmap_mode

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:
