Hi!
I've just ran Terragen 4 Beta and noticed that the sun is shining through the mountain. Is it a bug?
That has been part of TG all along, but you can get rid of it by checking 'receive shadows from surfaces' in cloud or atmo nodes.
Thanks, Dune! That solved the issue. I thought this kind of setup shold be enabled by default.
It takes longer to render, so it's better to keep it by choice, if need arises, like in your case.
