Mountain size is 12km x 12 km Everything is named, layered and organized properly.
Model is created by a displace map meaning you're in complete control over poly counts. You may keep it low for background or game assets or go as high as you need. 8 K displacement map has enough details to support that.
Bump map is generated from 500 Million polygons version of the mountain model ( supported by the displacement map ).
You can control how much snow is covering the mountain by simply adjusting the mask ( as seen in preview images ).
By nature of FBX & OBJ formats, model is collapsed so it's not possible to adjust poly counts for these 2 formats. Also materials are lost for these 2 formats but you can assign them by using the provided textures.
