Cliffs addon - Half-Life

Cliffs are tedious to make. However, triangulating brushes or using tetradehons everywhere, especially on a large scale, can lead to more resources being used than necessary. You can make good looking terrain using quads, and not cause invalid strcuture solids. The following map will show how quads can be used to create terrain. Instead of using the vertex tool, use skewing. Skewing will almost never cause invalid structure errors, thereby keeping quads a possibility when making terrain.

The ZIP contains a copy of the BSP file to see the results in-game and a JMF, which can be opened in J.A.C.K.
