    Does anyone have any idea on how to soften edges to make a pile of sand or dirt look more realistic? I created a landscape and made adjustments to look like the pile shape I want but it has a real hard edge. I would like to soften it up.

    How has the “pile” been made?

    You could:

    -Put a very small noise on the pile and use a displacement (with SubD displacement in the material)

    -Make the pile a volume and use a volume shader on it to give it a bit more depth

    -Add sub surface scattering which would allow more light to penetrate through a little – sand grains are usually translucent so the top layer will let light pass and reflect back out.

    – do an xpresso and Thinking Particle sim to build a pile of sand (time consuming and memory intensive)

    – use a third party plug in to do a fluid simulation and then apply particles and geometry to the backed sim (sand is just a chunky stubborn fluid)

    – use a very small cell noise shader and put the noise in the reflectance channel. This will add sparkle and life to the sand – add this to the deformation idea above and it has promise!

    – populate a “hard” cone shaped object with thinking particles on the surface only and that will give you the little grains and you can have it “shift” with gravity or a pushapart on a voronoi fracture every once in a while to add life.
