Erasing Paint

1.

To erase a section of paint, click on the Paint Buffer Eraser tool.

2.

Click and drag to erase paint from the paint buffer.

This does not affect the underlying paint baked onto the model, only the paint in the buffer.

Tip:  You can edit the brush details for the eraser (brush shape, size, and so on) the same as you would for any other brush.

3.

To clear the entire paint buffer, click the Clear the Paint Buffer button.

Mari clears the contents of the paint buffer.

Note:  You can also clear the paint buffer by pressing Ctrl/Cmd+Shift+C.

This video shows the workflow using Mari 3. Even though the Mari 4 workspace is different, the workflow remains the same. To have a look at the main UI differences, see Mari 3.3 vs 4.0.
