Terrain Generator includes a number of libraries and assets made by other people used under either the CC0 or MIT license. I've tried to make sure I list them all in the about box, but the problem with that is I can't include links to the sources. So I thought I'd post here with all the links.

Textures from polyhaven.com, ambientcg.com and cgbookcase.com

Brushes from CGTricks.com
