It's all good. I just wanted to be certain. I just want to clarify that he released this map as a modding resource. My mod would only require that his mod also be installed and in use when my mod is running, a dependency/child. I have however found a different map that I could utilize for my mod made by a different creator that is a public modding resource.

But essentially if I just take his map and modify it by adding/removing from it, I can reupload his map for public use and/or use it in my mod?
