The selected render system affects which renderer is used by Ogre. This affects the OgreMax Material Viewer as well as the shader programs that appear in the OgreMax Pass. Note that if 3DS Max is configured to use OpenGL in its viewports, the OpenGL render system will not be available.
If the standard 3DS Max viewports are configured to use OpenGL, selecting the OpenGL Rendering Subsystem will disable the use of the OgreMax viewports and OgreMax material viewer.
Resource Locations
These identify locations where resources used by the scene, such as shader programs, are located.
Export Resource Locations - Indicates whether the resource locations should be exported. If they are exported, they are converted to be relative to the directory containing the exported scene file.
Base Directory - The directory that newly added resource locations are converted to be relative to. This value is determined based on the combo box setting:
3DS Max - The 3DS Max installation directory is used as the base directory.
Project - The currently configured 3DS Max project directory is used as the base directory.
Custom - A custom directory is used as the base directory.
Resource Locations - A list of locations containing resources used by the scene.
Resource Locations
These locations are exported, but not used within 3DS Max.
