After the great response and feedback after shipping the project, I’ve been at work adding in more custom world-generation and blocks as was requested.
I first started by adding in some boulders to the surface of the desert made of smooth sandstone which add some variation to the surfaces. These rocks are distributed using noise to make sure they are not just evenly scattered across the desert to add additional variation.
I then turned my attention underground as the only underground biomes we currently see are the deep dark and lush caves. I created a new sandy stone block and created patches of them near the surface which can generate dry grass or sand blocks on top of them, this helps make the underground feel a bit more varied and not just monotonous stone.
I want to add some more custom content underground, maybe buried structures or relics. Feel free to leave feedback on what you’d like to see!
