NEW IN R20
Use this setting to define the Rock Material’s base color, which can then be layered with all types of Noises to create a rock or stone-like structure.
These three settings can be used to add various noise patterns to create any type of rock, as shown above. You can use Fine Grain and Coarse Grain to create many types of rocks; Large Structure can be used to add variation for large rock formations (e.g., an entire cliff). Small values will disable the respective effect, larger values will strengthen the effect correspondingly.
