UV Mapping My Hill

For my environment, I wanted to model most of it in maya before taking it in unity. 1 reason being that I am a lot more comfortable with using maya at the minute and also I feel I can do a lot more with my environment manually which im hoping I get a few more marks for. In my scene, I have my boot which sits on top of this little platform. When modelling this, I found it pretty straight forward, at times having to change things to suit the boot but when it came to texturing, it was very challenging. 1 reason was none of it was unwrapped. It was all separate projections from different angles which meant I had to do a lot of going from photoshop to maya to check the different parts of the UV map that I had textured didn't look different. Here below is the final UV map that I used. As you can see, theirs a lot of different textures which made it very difficult to work with having to use the clone stamp tool an awful lot to get things right.
