So I would like to be able to generate some desert like terrain but I there is no way to do that currently. I think it would be cool if we could choose the main material that is used in terrain generation and just have grass as the default. That way, it would be a lot easier to generate some biomes that we would currently have to build by hand such as a snowy/icy biome.
All the code for the plugin is public on ROBLOX’s GitHub page. Wouldn’t be hard to mod it to allow different materials.
