Fog is no longer a property of a zone, and any existing uses of the old fog property will disappear from worlds opened in this build. Fog is now controlled by placing a fog space node into the scene. The zone containing the fog space node is automatically fogged, and other zones may be linked to the fog space so that one fog space can be used to fog areas covered by more th...")

You can tell the engine to load this game module by editing the file <code>Data/CFG/Variables.cfg</code> and changing the value of the variable <code>$applicName</code> to "Skeleton".

This only affected point lights, and could cause the illumination to drop out too early as the camera turned away from the portal. * Implemented a new diagnostic mechanism that displays light regions. This is toggled on/off by using the command <code>rgns</code> in the command console. The...")

This flag is useful for lights that are attached to other objects (like a character). It's possible for a character to be in one zone, but the light that he's holding to be in a different zone because his a...")
