Thank you! I made a blockout of cubes in Zbrush and started sculpting a blockout from there. I'm going to create a post for the whole project soon if you want to follow it. Again, thanks for the kind words and your advice! I'll probably be doing that through vertex painting in UE4 :)
Thanks, @VisualTech48 and @BIGTIMEMASTER for the comments! I like the idea of the colors but I'm probably going to add that by placing down foliage and maybe vertex painting some moss on the stones etc. For the lighting, everything is as good as default at the moment. One of the main things I want to learn from this…
