Might help if you mentioned the headset@AncientWorlds - They posted that a bit further back:
I’m sorry I should have included this to start with. I’m on windows 10 with a valve index,@UNGOVERNABLE - AncientWorlds might be on to something. When you launch Open Brush - have you already started SteamVR? Can you see the home or the blue grid plane in the headset?
