Nice level. Very creative. Never thought of stacking up the rocks in that way.
For particles, they can be finicky when testing over and over.
Re-start GG if something doesn't seem right. Better yet, that's why AmenMoses'
tools are the way to go. Personally I'd save particles for the very last add after all
the rest of the design. But maybe it'll go pretty easy.
Have you thought of moving the new dynamic sun shadows + visual sliders to see
what that could produce?
