Beta 1.0 now almost finished! - Also in https://www.planetminecraft.com/mod/singularity-4927345/
Singularity is a mod that adds various random things. A lot of this mod is incomplete, but I look forward to expanding it. Most of this mod is progressive, post-end dimensions, and so forth. There is also many decorative features, and since this is my first mod, you may have to use JEI or something related to that for complex recipes. This mod was also originally made for 1.12, so please don't complain about the old textures, although now they mostly may be updated. Anyway, thanks and leave support! (if possible)
Added.. stuff
Sorry for the late reply, but no, I'm not talking about using those tree presets. Instead, you can grab a few structure blocks (look up structure blocks on the Minecraft wiki if you need help with them) and save a tree as a structure (make sure you fill in the blocks that you don't want to be part of the structure with structure voids, and then import those structures into Mcreator and make a structure that spawns throughout the world.
