Selecting Edit → Preferences… from the main OpenSim menu bar.
In the Preferences window that appears, double click on the value of the option you want to change and enter the new value. To save changes to the preferences, click OK.

Details about the available preferences are given in 3D Window Display Preferences, the table below. These preferences are saved and will be applied during the current session of OpenSim, as well as any future sessions of OpenSim.

3D View Window Display Preferences

Option Name	Default Value	Description	When Applied
BackgroundColor	0.0, 0.0, 0.0	RGB (red, green, blue) values for the color to be used for the 3D View window background. Values range from 0.0 to 1.0.	When a new 3D View is created. Can be changed either here or using the Toolbar of the 3D View window.
Markers Color	1.0, 0.6, 0.8	RGB (red, green, blue) values of the color used for the virtual markers in the model. Values range from 0.0 to 1.0.	When a new model is created or loaded
Geometry Path	../Geometry; Geometry	A list of directories separated by a semi-colon that specify where OpenSim should look for geometry files (.vtp files). When a model is loaded, the directory containing the .osim file is searched for geometry .vtp files, as well as a directory with the name "Geometry" that lives underneath it. If a file is not found in these 2 locations, the directories specified in "Geomerty Path" are searched in order. The paths are specified using the Unix format and are defined relative to the OpenSim installation directory.	Instantly, as well as to subsequently loaded models
DisplayOffsetDir	X	Direction to offset display of models after the first one is loaded (X, Y or Z)	Applied when the next model is loaded
AntiAliasingFrames	0	An integer number between 0 and 4 indicating how many frames are overlaid to achieve the impression of anti-aliasing (blurring of edges to reduce jaggies on straight lines)	Instantly. Be aware that a value of 2 or higher slows the display significantly.
NonCurrentModelOpacity	0.4	A number between 0 and 1.0 indicating the opacity of models that are not designated the current model. A value of 1.0 means that non-current models are opaque, so current and non-current models look the same. A value of 0.0 makes non-current models completely transparent, so only the current model shows in the 3D View window.	Effective the first time the current model changes after setting this value
Debug	0	Debug level. Setting value greater than 0 (max =3) outputs verbose text to the Messages window, also when an exception is thrown a detailed stack-trace to help with troubleshooting is shown.
Persist Models	On	Whether to keep track of open models, motions and camera views so that they are restored on opening the application.	Exit/Re-entry into the application.
