The Macintosh version of LightWave features a titlebar menu labeled Special which hosts a number of Mac-specific options.
⌘ Mimics Control Modifier
On by default. With this option on, the command key (⌘) can be used instead of the Ctrl key for Ctrl key shortcuts, like Ctrl-L for Limited Region. Be aware there can be a conflict when ⌘Fn Mimics Fn is also on for Ctrl-Fn key shortcuts, like Ctrl F5 for the Effects window.
⌘ 'help' Mimics 'insert'
On by default. The Insert key on a Windows keyboard pauses playback of a scene, but a Macintosh keyboard doesn't always have one. This entry enables the Macintosh Help key to replace the Insert key.
⌘ Fn Mimics Fn
Opaque Popup Menus
On by default. When off, popup menus and dropdown lists have a slightly transparent feel.
Opaque Utility Windows
Off by default. When enabled LightWave panels that cover any portion of the main window will become semi-transparent during mouse manipulations within the main window. This helps with viewport manipulations without moving the obscuring panels.
Scroll Wheel Mimics Option-Mouse
Off by default. This allows a mouse bi-directional scroll wheel/ball to manipulate viewports as if holding the option key while click-dragging the mouse pointer. This aids in viewport navigation.
Allow OpenGL Stereo
Off by default. Some Macs have display adapters that are capable of Stereo OpenGL (quad buffers). Enabling this feature on display adapters that do not support it can be risky, so this feature is disabled by default. A restart of LW is required when changing this setting.
Off by default. When on, LightWave fills the screen completely including the menu bar. The mouse needs to be moved to the top of the screen to see menus.
Allow Hi-Res OpenGL
Although LightWave 2019 supports HiDPI monitors automatically now, this menu choice is still a valid one. If your graphics card is not powerful enough, leaving this menu item in its default Off state may result in a faster OpenGL display. Layout must be restarted after changing this setting.
