Mountainous Red Mountain is great, but https://www.dropbox.com/s/59ygniqoa92jna0/PLX_MRM_rock_17.zip?dl=0 widely used mesh done combining simpler rocks in nifskope would benefit from stripping https://www.dropbox.com/s/hifeystivjwpxvm/mashed.jpg?dl=0.

Any 3d tool expert up to the task (I thinks something similar to occlusion culling may be needed)?
