This is a 4 sided mountain done in Quadspinner Gaea. I will use it as a environment in UE4 as far mountains. I don´t spend much time on texturing this, cause most of us will use his own material.
It also can be used to texture this mountain in Quixel Mixer, Substance and so on. You can export your maps from there.
This .fbx file comes with a 2k Albedo, Normal and AO map. Feel free to use or share it.
You can see some Screenshots without any texture in my Blog.
