Managed to use 3.5 gig memory rendering this with so many plants.
I'm using the Alpine Fractal, not function nodes, to produce the cracks on the rock domes which are planet objects.
Chanced upon an Alpine configuration that does make cracks, however Terragen likes to change the values when I save and then
reopen the file. Took me a long time to figure out why the cracks appeared in some renders and not others.
Then I saw that the values for smallest scale will not always stick around and need to be re-entered before rendering.
This is the first time I've had values change like that. Fortunately they are legal during the render, just,
apparently not always legal to save. Not sure if it is a great method, but if there is any interest I will post the configuration.
Tried to use some population color variation ideas from the forum on the domes, however in the
foreground the bushes are a combination of two renders in slightly different colors, mixed
where desired in Picture Window Pro, where I also adjusted levels.
