Under Edit > Preferences > Hotkeys > Camera Control, I set the Hotkey Preset to SolidWorks.
After I close and restart Keyshot, the camera controls revert to the default. When I open the above settings window, the Hotkey Preset is correctly set to SoliddWorks. After I close the settings window, the camera controls work as they should - using the SolidWorks presets.
This happens every time I close and reopen Keyshot and started after upgrading to Keyshot 10. My current version is 10.2.113.
I am unable to reproduce the issue. If you upgraded to KeyShot 10 using the upgrade installer, please make a backup of your current Resources Folder to save any textures and materials. Then please uninstall KeyShot and try a fresh installation using the Full Installer.
