The Slope Paint tool will allow you to alter the terrain slope locally.
As with any other paint tool inside the DreamScape Terrain Editor, you use the Slope Paint tool as follows:
Push the Slope Paint button.
Move the mouse pointer to the desired position inside the Terra Editor Preview window.
Click-hold the left mouse button to start painting, and continue holding it during the paint process.
Brush Size - Controls the size of the brush. You can enter the value, or simply drag the slider to set the brush radius in percentages of height field size.
Brush Softness - Defines the percentage of the Brush size that will be used to smooth the Slope Paint effect along the radius from the brush center. With zero softness (Brush softness=0), slope changes will be applied uniformly over the whole Brush size area.
Slope - Negative values of this parameter will increase local slopes, while low altitudes will be lowered more then high altitudes. Positive values (as shown in the rollout above) will increase low altitudes much more than high altitudes.
Strength - The strength of the Slope Paint tool.
If you are using pressure-sensitive digitizing tablets, you can control the Size, Softness and Strength values with the pen pressure.
