Hello everybody! I had a lot of unused heighmaps and alpha masks clogging up my terrains folder, and since I wasn't using them, I decided to upload them in case anyone else wanted some use out of them. There's a lot of variety in here, so I'm sure there's something for everyone! :) the names match (aka sampleheight and samplecolor) so it's easy to tell what goes where. Here's a screenshot of what's in there.
