They're all rocks, Jeff - big rocks, little rocks, tall rocks, thin rocks, fat rocks....😁

Ah yes, but that's a henge rather than a stone circle.

I've gone back to working on the waterfalls for now, but I'll see if I have time.

A bit like this (though these are very raw at the moment and need some roughing up)

This may not be the problem, but check that you have the latest installers for all your software. Things that have been lying around in your download folders for a couple of years may not be all that useful.

All installers should be run as administrator by right clicking the installer.

Make sure you allow CC3+ to open at the end of any installation process where the default setting is for it to open, and that you reinstall the latest update at the very end - even if you've already reinstalled it once early on.

This is very true, Joe. If all circles were as perfect as the day they were created I could just put fractalised polys of stone there and give them strange looking shadows, but there are also fallen and leaning stones that can give a much better feel for the nature of all the stones. Well, that's what I hope anyway.
