In this first Unity3D Tutorial, I will show you how to create nice, detailed terrains using Heightmaps I got from google and implement them into Unity3D to make a nice level. I also show you some ways to make your scene look really nice with textures and a skybox. You have the right to use this terrain in any of your games, I am not really concerned. You will need an image editing program such as paint, GIMP or Photoshop to complete this tutorial.
