Faceted Shadows

I’m having some problems with faceted shadows with physical sun or a maya directional light.

The only way I’ve been able to get rid of them is to render the surface as a subdiv with high divisions, which slows everything to a crawl.

The surface does have some spikey polys, but I would think a subdiv with 2 divisions would fix it.

It also shows up with dirt. Is the only solution to render with high subdivs?



It might help to increase the shadow bias for your direct light a bit.
