Creates a dynamic shadow-casting light that affects all objects in the world. Used for the Episode Two flashlight.
Enabling multiple shadow maps
Valve's games only allow one projected texture to cast shadows at a time - including the player's flashlight! To surmount this, shadow casting can be disabled with the enableshadows KV, or for a proper solution a programmer can perform this fix:
CClientShadowMgr::Init() - bool bTools = CommandLine()->CheckParm( "-tools" ) != NULL; - m_nMaxDepthTextureShadows = bTools ? 4 : 1; // Just one shadow depth texture in games, more in tools + m_nMaxDepthTextureShadows = YOUR_CHOSEN_MAX;
Garry's Mod has already had this done. Thanks to Garry for sharing the code!
