For the initial landscape testing, I figured I could just use a mesh from Blender and have the terrain tools in Unity add plants and grass. Well, it turns out that doesn’t work. Oh well, at least the Terrain tools in Unity are easy to use, so I can just duplicate the terrain.
But the test did have one good result: my dinosaur looks quite good when the textures are applied to it. However, the diffuse isn’t quite the right colour, so I need to tweak it a little.
