Setting the Clone Stamp Options

1.   Start Mari and open your project.
2.   On the Tools toolbar, click to select the Clone Stamp tool.
3.   Open the Tool Properties palette.

The current properties of the selected tool display. Scroll down to view them all.

4.   To customize the brush you're using for your selected tool, set the options under the Tip and Geometry
sections.

These are the same options available for brushes in general - see Configuring Brushes.

5.   To set the brush strokes to start relative to the source point, click the Relative checkbox under Texture > Image.

If this is not selected, the clone brush strokes always start from the source point (see Setting a Start Point for examples).

6.   To turn the onscreen preview on when cloning from an external image, under Texture > Preview, click to turn Onscreen Preview on. Set the Preview Alpha to your preferred value (higher makes the preview clearer, but makes it harder to see the current paint in the channel).

As you click in the external window to change the source point, the preview moves around on the main canvas.

7.   To set whether Mari zooms images relative to your view, turn Scale Lock on or off, under Texture >
Transform.

If this is on, Mari locks the image size relative to the model, at the current zoom level. If you zoom in or out, Mari also zooms in or out the image that you're painting through. If this option is off, the image scale won't change when you zoom in or out.

8.   To set whether Mari resizes source images to fit the paint buffer, change Reset Size setting, under Texture > Transform:

ToOriginalSize - Displays and clones the source image in its original size, in screen pixels. For example, a 1024x1024 image takes up 1024x1024 pixels on screen. This is the default.

RelativeToPaintBuffer - Displays and clones the source image resized so that one pixel in the image matches one pixel in the paint buffer. For example, a 1024x1024 image in a 2k (2048x2048) paint buffer appears onscreen as half the size of the paint buffer.

9.   To set whether Mari preserves transformations when you switch source images, change the Auto Reset setting, under Texture > Transform:

DoNotReset - Preserves any transformations (such as moving, resizing, or rotating) you have made to the source image that you're cloning, if you switch to using another source image. This is the default.

Reset - Resets the image to the default size, location, and rotation, each time you switch to another source image. For example, if you're using a 2k paint buffer and a 4k image, the image always appears to be twice the size as the paint buffer onscreen.

Tip:  Use DoNotReset if you want to clone several images of the same size. This is specifically useful if you want to switch between using multiple 4k textures, as it saves you having to resize the source image
preview from the huge default every time you switch.

Now that you've set up how the clone tool works, you can get on and start painting.
