Annotate Tool - MARUI-PlugIn/BlenderXR GitHub Wiki
The Annotate Tool allows you to draw and write in 3D in VR.
When the Annotate Tool is active, pressing the trigger will create a new line at the tip of your controller.
The Tool Objects Menu allows you to set the color for the stroke.
When you hold the Control Button, the tool will function as an eraser, deleting drawn strokes.
