Shadows group is a combination of '''_cs''' (cast shadows) and '''_rs''' (receive shadows) [[entity]] keys used to control how entity cast lightmap/vertex light shadows. A numbers should be used for shadows groups (1, 2, 3, 100, 1000 etc.), negative values are allowed.

Shadows groups are applied during lightmapping of entity using this rules:

#Receive shadows is 1: only receive shadows from objects with cast shadows 1 (the worldspawn cast shadows).
#Receive shadows is > 1: only receive shadows from objects with same abs(cast shadows) and worldspawn.
#Receive shadows is < 1: only receive shadows from objects with same abs(cast shadows) and no worldspawn.

By default [[worldspawn]] and [[func_group]] have cast shadows and receive shadows 1. All other entities have cast shadows 0 and receive shadows 1.

+Mapper can make levels to look better if entities which are known to be static (such as func_walls, trains rendered in the start position etc.) will receive explicit shadow casting.

+==Usage example 1: Trap made of func_train==
 You have two func_trains one replacing other during trap activation (Blood Omen spike traps). So you need both trains be rendered in their destinatino position, having world shadows cast upon them, but not casting shadows from each other.
