I tested this with these three mods trying to replace the copper ore spawning in the caves and cliffs mod with stone, netherrack, air and iron blocks. I tried replacing the mudstone that spawned everywhere in the village and pillage mod with stone. and i tried replacing the quark basalt with the nether update basalt. all useing mcreator mods. its worked with other mods i use.

All three of those mods are closed source and All Rights Reserved, so I cannot do anything special to add support for them. Also, 1.12.2 is no longer supported.
