As this program mainly is a painting package, the existence of the well definied brushed is cruicial. The first tab on the control panel - called Presets (F5) - has all the brushes in different categories. We can select from the existing brushes here, or also there is a possibility to create new categories, or brushes.
The second tab on the controll panel contains the Brush and Painting settings. DP has a very wide variety of settings what we can adjust here, from the brush shape to the texture types.
Most of the functions are quite straight forward, so I would mention only the most important bits.
First of all we can select brush shape styles from the selection was given to the DP by default. Of course we can extend this selection by creating own shapes and put them into the ResourceBrush folder.
We can also create canvas bitmaps (ResourcesCanvas) or select from the defaults by clicking on the grey triangle next to the Brush Canvas radio button.
The textures section is probably one of the most important feature (IMHO) , where we can assign different color-bump-specular maps to the brush. There is possibility here to change the hue/sturation values of the image and also the size and proportions. There is a nice opportunity to create proper brushes for very difficult surfaces, and have the chance to paint all the maps in the same time. Dont forget to make all of these maps seamlessly tile-able.
