Using the effect 'as is', i.e. without any additional parameters, reproduces the old appearance of the dirt runway effect in ALS: | |||

With the original dirt runway texture mapped to a small size and framed by less structured dirt, also a compelling result can be achieved: | |||

Using grass as the overlay material blends the runway outline nicely into the airport keep: | |||

Finally an example of diffuse sand patches blended into each other by low frequency noise and a large value of the transition in the filter: | |||
