My first submission to the Asset Store Hidden Gems: It's on the front page, and it's on sale, $25 instead of $65.
I personally bought Relief Terrain Pack 3.2 AND Terrain Composer, but they're so dang confusing.
I'm sure if I sat down, I could figure it out, but this Gaia asset looks incredible; he makes an entire level in THREE MINUTES.
If you can spare $25, pick this up. I just did.
