Ideal Intersection Settings for Cracks

WAS · October 22, 2015, 04:13:50 AM

What would be the ideal settings to use for following cracks in terrain? I've been trying to get this down for some time for awhile and can't seem to get anything correct. Lets say I have a rock face, now Imagine water pouring down it's face, now imagine time, particulates, and moss gathering in said intersections. How might I achieve this in dynamic terrain without masks?

This might get you thinking - look inside the cube object.

So it does require a "somewhat" level of masking? This being the displacement?

Yes but in this case the mask comes procedurally from the displacement. I haven't explored this fully and I'm sure improvements can be made.

When I apply this method on terrain outside a object, the displacement as a mask (using it's color) doesn't seem to match the detail of the terrain. Any ideas?

Compute terrain interferes with its larger patch size.

Thank you oh enlightened one! Much appreciated, this actually explains a lot.

Sorry I haven't replied, I've been away - Dune has it!
