Painting

Read about elements of painting within Mari and the different tools you can use to achieve this. Familiarize yourself with features and functionality, as well as specific workflows you might be interested in. Here are some painting basics to get you started.

Painting in Mari is similar to other standard paint programs. Paint using the various tools, then bake it onto your model. Most tools work on unbaked paint, but one or two also work directly on the baked paint on the surface. Each tool has a set of keys that control how it works. By default, the option keys for the current tool are shown on-screen at the top of the canvas.

Paint Tools
