I Dont know or its a bug or its something, but i have 32bit computer and when I Install mods in folder, forge wont load it says only
Downloading nessy-all and starting forge but minecraft launcher wont opens and it dont run
I don't see anything wrong this might be an issue with world painter. Is there a way to see if world painter actually tells the blocks to get generated or not?
Could you be more specific on what you want the multi block structure to do because it will affect the way you will do things as there are a few different ways you could do it.
