Rock Factory landscape example is included with Rock Factory. It features terrain detail meshes, level of detail, terrain integration and a variety of rocks, stones, pebbles and boulders.


CaptureInspector RFRock
The custom editor allows you to keep in control with the many parameters the engine provides, by only presenting the ones you need and hiding the ones you don’t. Switch to advanced mode to really get in control. The displacement map overview allows you to give visual feedback for all of the settings you’ve changed.

CaptureInspector RFRock Material
Rock Factory comes with its own shader which you can use on your rocks. You can switch parts of the shader on or off, allowing you to reduce GPU cost. It features overlay blended detail maps, custom specular lighting calculation and edge wear effect (only usable in combination with rock factory). You can, however, always use any other shader you like, as all rocks are real non-GPU generated meshes.
