I have created my first terrain in Unity using Heightmap.I used a heightmap created in Photoshop.
Actually the terrain looks fine. It has only two glitches:
1. On the bounds of the terrain it has vertical walls which - according to the heightmap shouldn't be there. Why such thing occured there?
2. The terrain looks like it has mesh which density becomes larger as it gets closer to the bounds. Is it normal? I am afraid that it can slow down framerate.
Below are the images.
