Painting

• Anti-aliased, smooth brush edges, and a Softness slider for every brush (oil brushes, eraser, rag, smudge, clone, airbrush).
• New Airbrush tool: a soft spray that builds up the longer you hold it, with a Flow slider.
• Paint distance and resize speed sliders; the left grip opens the colour picker.

Rigging

• Quick IK reworked: the IK target is made at the end of the chosen bone, pointing up, then you place the pole with the trigger (the grip skips it). Both are animatable (+). Running it again replaces the old IK.
• One Symmetrize button that mirrors every .L/.R bone across X or Y (rigs built facing any way), keeps the chain connected, and copies bone constraints aimed at the mirrored IK and pole.
• Delete several bones at once.

General

• The Settings window has Undo, Redo and Save (a never-saved file goes to Documents/VR Studio).
• Robustness: a failing visual helper no longer stops the controls; errors are logged to vr_studio_errors.log in the temp folder.
