To start with the objects were unwarpped which I didnt have to do because they are very simple objects but I unwrapped them just incase. I then went to search for textures that are suitable for the environment that we are creating. For the ground and mountains I used this texture map as a diffuse map (except I made it abit yellow-ish).
At first I used the dark texture to the mountains and the ground however everything ended up looking like chocolate, therefore I change the colour to make it more yellow-ish but I used the dark one the polygons which are in contact with the water.
I also used the yellow one for the ground, as I wanted the grass to be a mixture of grass and sand I used vray blend material were it blends two materials together. I opened photoshop filed the layer with black and I added white areas so it is a mixture of black and white and I then used this file to create where the grass would go and were the sand would go.
I created the bump, spec, and displacement for each of the texture maps. For the ground those were the texture maps for it:
For the rocks the texture maps that were used were:
Final results:
