A mod I made that allows you to randomly retexture an area using a block pallete you select. It also contains a building guide for building differently shaped arches. The arch builder even works with chisel and bits microblocks! (IIRC only in 1.12 because c&b wasnt out for 1.15 when I wrote it) Here is the C*rseForge link. And the same files hosted here.I plan on writing an actual effortpost about it here, eventually, once/if I revive the project.
