(HELP WANTED) Environment/Structures Thread

I'm am 13 years of age and have been working on a game for a year. Within this time period I have had many difficult problems to surpass. This time I cannot seem to manage a mountain or any sort of structure. I have attempted to use cinema 4d to generate structures but did not manage please help.

Hello,

If it is just the mountain, and I understood correctly, maybe you could check this out: Mountain.turbosquid.com

Thank you very much for responding I checked it out, but how can I split textures like that in Unity 3D?
