The materials generated by the AI also dont appear to have any normal data, creating this flat/smooth looking texture.
What can I do to improve this? I plan on potentially littering the hills in a few boulder meshes, but I dont think that lack of detail is the only problem here. What do you guys think I should do with this?
I would say that the following image you are trying to recreate, drag it to the side of your screen and use the sculpting option to improve it and you can also paint the edges of the terrain with a different material and smoothen the terrain to make it look realistic, adding some sun rays and paying attention to detail may at least help you with what you are trying to achieve.
Roblox just came out with a new race template. They did some cool things with the mountains in it. All terrain based. Kind of looks a bit like what you’re looking to do here. You may want to take a look at it.
