Any better info for using the bedrock option in the erosion node? besides the docs? They are thin on exactly what this does or how to implement it and I'm pretty curios.

Bedrock lets you specify an incoming layer to be a reference height. This has two uses:
1) You can animate the incoming bedrock layer to create up-lift and other tectonic effects
2) You can adjust the hardness of the rock with depth using a ramp. This is relative to the bedrock height, letting you have strata that aren't flat.

Are there any definitive examples of how to set this up? A demo scene? I can't find examples in any videos unless I missed something, very possible ;-)
