Yeah this is the method I use as of late as it allows me to create large terrains very fast. The materials set up in vue usually takes me a day or two as I am still learning vue and find that it is still a lot of trial and error until I get the results I am looking for. I then spend another 2 days on the ecosystems and setting up the atmosphere and usually have good renders that I am happy with at this point.
The big problem with vue is the excessive render times but I am very fortunate to have access to a lot of computation power at work.
