Heightfield Erode on geometry/VDB

[reeson 0]

Hey guys. Is there a way to use heightfield erode on a geometry or VDB. Let's say if I have a box, and I would like to apply erosion, how would I do that? Cheers!

If you treat it as part of a heightfield you can erode it, then get it out as a polygon (printscreen and hip file attached):

Thank you. I was looking into heightfield project node, but what if you want to erode a more complex geo, like this cube?

If you are trying to make a rock maybe this could help:
