This section will be heaviliy extended soon, as customization is a high priority for SkySketch.
General Settings:
Various settings, such as the menu scale, menu curvature and movement speed can be tweaked in the settings menu, with independent values for screen and VR mode. Try checking which sizes feel the most comfortable for you to work with!
If you accidently edited or deleted some of the included standard brushes and want them back, you can use the "Restore Resources" button to do this. Not that any existing files with the same filenames as the resources content will be overwritten, so make a backup if you added something on your own that you don't want to risk losing, or put it in a separate folder before running the command.
Performance can be enhanced by opting for a lower undo step or purge threshold setting. Lowering the purge threshold means that internal cleanup operations will happen more frequently. This can enhance your overall performance, but while the cleanups are executed, there may be a small freeze each time - usually just a small moment, if noticeable at all. This will happen once every few minutes, depending on the setting.
Hotkeys:
Key/Button remapping will be available shortly. The list of default keys can be viewed here: Hotkey List.
SkySketch VR Input Settings:
The "VR Input" Settings section lets you switch between left and righthanded mode (which is unneeded for Vive Controllers, but important for other controller types such as the Index Knuckles!). You can also swap between a visor and a handheld style for the main menu. Offsets for both, the position and the ray from your VR controller can be tweaked in detail. Presets for a range of common headsets will be available soon.
If you ever tweak settings to the point of breaking in VR mode, try going back to screen mode to undo that - and vice versa. The "Default Settings" button at the bottom allows you to restore all SkySketch settings to their default value.
