Liquid Studio is a product born from TwistedBrush Pro Studio but with a focus on creation of individual objects that you might use in other Pro Studio or other art software and with a simpler, streamlined interface. The Liquid paints allow you to model and shape your objects and then paint them with the included brushes with the results being crisp lines you might see in illustration software but without the need to mask anything. You can even continue to shape your objects after they are painted.
