Custom Buttons by 3dEE
Custom Buttons | Void
This Button UI is not intended to be on screen all the time, rather to be invoked as needed. Set the hotkeys in Keyboad Settings, the command to look for is 'Show Buttons Toggle'. I have mine set to tilde (~), I've also set the 'Next Button Page' to ALT+1 for convenient cycling of the 2 pages.
Extract to 'C:\Program Files\Silo 2.1\Preferences' creating the void folder. Go to Editors/Options > Button Settings > Load and load the SIP file. Copy the SIP file to 'C:\Program Files\Silo 2.1\Preferences\Presets\Button Settings' to get it in the Presets dropdown in the Button Settings window.
