I'm trying to create a realistic looking mountain range with a ground plane. To begin with, i'm new to not only Octane but 3D in general. I'm assuming that what i'm trying to create shouldn't be too difficult but i'm not having much luck. I've downloaded various Octane texture packs and also texture images from some of the texture sites online but i'm wondering if anyone can direct me to some resources that can help me to create something more lifelike. None of the tutorials i've found have been of much use either. I've attached an image of some references i've pulled.
