In this recipe, we explored three height painting tools. The first areas were raised straight up to a height of 2 using the Set Height tool. The Set Height tool is useful for quickly raising or lowering areas to a specific height. However, it leaves very steep walls between areas of different heights. It's also great for returning areas of the terrain back to zero.
The second tool we used was Smooth Height. This tool is used for finessing the final quality of the areas of the terrain where the height changes are too steep, so it is often used in combination with the Set Height tool.
Finally, we used the Raise or Lower Terrain height painting tool. This incrementally adds (or with Shift pressed, subtracts) to the height of the Terrain areas being painted upon. In combination with complex brushes, it allows us to quickly add complex details to areas of the terrain.
