Hello, I have been working with Unity since around August of 2010. I started on a project (with a small team of friends from around my country) to create a BIONICLE-themed RPG (BIONICLE is a toy line created by LEGO in 2001 and discontinued in 2009). Much of the first few years of story revolve around a tropical island known as Mata Nui, thus it is essential that this island appear in our game. One of us took the official map of Mata Nui, touched it up a bit, and converted it to grayscale. I did a bit more work touching the image up in GIMP, then exported it as a .sgi file. I imported the .sgi fine into Terragen and used that to convert the file into a .raw file that Unity can use for a heightmap. I then imported the heightmap into Unity. In Unity 2, this all worked just fine, and I ended up with a nice terrain. In Unity3, however, all i end up with is a bunch of spikes, like a sawtooth saw blade extended across the whole terrain. Does anyone know how to easily work with Unity3 heightmaps (preferably with minimum use of third-party applications), or at least how to import said heightmap effectively? A tutorial would be nice.
Please don’t tell me to Google it, I already am.
