I'm in the process of re-doing the options gui and while I've been able to figure out how 90% of it works but I cannot find where the sim groups that contain the graphics quality preference level array objects that are used in scripts/gui/optionsGui.cs are defined. I am talking about MeshQualityGroup, TextureQualityGroup,LightingQualityGroup,and ShaderQualityGroup. I've searched a ton of the scripts and have yet to find out where these are defined. I don't necessarily want to change them it just bothers me that I can't find them. Anyone know?
