Hi resiFrog, the RPGMaker MV tileset B-E have a maximum size of 768x768, that's why I had to divide them. There's no actual way to have bigger tileset files, maybe with some plugins...
Yes, I know, but there is a lot of blank space for example in the "interiors 0 ", i don't know if you can fill with other tiles...or if i'm saying nosense sorry.
