I'm pretty new with the Unity and C# and, after a couple weeks of prep, I decided to dive straight into an FPS. Because I'm still new and I'm not even that confident with Unity, I didn't - and still don't - want to spend any money. A couple of days later however, I hit one huge problem. Graphics. I understand that there's no chance that I'm going to be able to get anywhere near AAA graphics, but I would like my terrain to look half-decent. Does anyone know any good, free, (preferably open-source) terrain-creating programs? I've already messed about with Unity's default, but it doesn't seem to do the job; it uses two many draw-calls, and it's super buggy. Thanks!
