Brush Collection

– Used to define a specific collection to pick brush objects from.

– In this example I created two Collections: Green_brushes and Orange_brushes
– By choosing the 1st or the 2nd Collection of brushes you let only the green or the orange brushes interact with the canvas.

– After clicking on the Brush Collection window you can choose the Collection containing the Brushes you want to interact with the Canvas.
