New to Terragen Sky, but first thing I noticed when opening the program, is that even after the default scene has finished rendering, it maintains 95% CPU usage continuously....is this a bug?


I don't use Terragen Sky, but i tried it.
My CPU goes from 2% 2.45Ghz to 100% 4.5Ghz


Hi Mike, welcome!

Did you mean the preview that automatically starts, or did you use the Render Image button?

It might still be progressively refining the preview, taking more samples to reduce noise. Does it say "Preview finished" below the Preview Mode buttons? You might try turning off all the cloud layers so it completes more quickly, just to test if it ever finishes.

Another thing to consider is that some of the preview modes will render a full 360, and they can take a while to complete. I wonder if that's what's happening.
Just because milk is white doesn't mean that clouds are made of milk.
