So while searching around for terrain generators in blender I found a plugin built into blender thanks to this tutorial:
http://tutorials.cgrecord.net/2014/08/create-mountain-in-blender.html
SO I thought what happens if I apply TGC's rock texture to it and put it in FPSC:R.. I ended up with this.. It was really easy to do and gives you nice mountains! I have attached a zip file containing the mountain in the pictures. For best results move it down on the z axis a bit once you have inserted it into your map.
Obviously I'm pretty rubbish in blender and don't really have a clue what I'm doing... but someone with more skill could probably make lots of prefabricated hills/mountains/caves using the generator and texture them better than me...
Edit: Put this in the wrong thread meant to put it in free models and media.. silly me...
