Image Options

When you are painting using an external image, you can choose to have Mari display a preview of the image, floating over the canvas. This makes it easier to see exactly which parts of the source image Mari is cloning when you paint. This is very similar to using the Paint Through tool (see Painting Through an Image or Gradient).

Mari can either scale the external image as you zoom in or out on the model while painting, or keep it at the same size. You control this with the Scale Lock setting: if on, Mari locks the image size relative to the model, at the current zoom level. As you zoom in or out, the image that you're cloning from zooms in or out too, so the cloned texture always stays at the same scale, relative to the surface you're painting on.

If Scale Lock is off, the image scale does not change when you zoom in or out.

Tip:  Mari copies textures you clone from an external image at the resolution of the source. Mari then paints these into the paint buffer at the buffer's resolution. For example, a 4k image provides 4k source texture for cloning, which Mari can then paint into the paint buffer at a maximum of 16k (the maximum size of the paint buffer). See Controlling the Way Mari Applies Paint to Your Model for details on paint
buffer resolution.
