source: code/trunk/src/libraries/tools/ParticleInterface.cc @ 7387

Last change on this file since 7387 was 7166, checked in by landauf, 14 years ago

added new macro to ConfigValueIncludes.h, "SetConfigValueExternal" for values with user-defined name AND user-defined section

added new config value for models to enable/disable LOD (aimed towards people which experience crashes when using LOD)
moved config value for the LOD of ParticleInterface to the same section (GraphicsSettings) using the new macro
