I should finish my improved rock meshes mod which is based on Correct UV Rocks. Here is the https://www.dropbox.com/s/5naerauemqu9j0s/WIP_smooth_correctuv%20rocks.7z?dl=1 which already includes all rocks covered by Correct UV, and a few more. But there are some missing which are not in the Correct UV mod, most prominently the bitter coast rocks (which already have a good uv map). My meshes are basically subdivided and slightly randomly sculpted, so the basic shape remains the same. They even use the vanilla meshes for collision, so they should be compatible with everything. Sure, On the Rocks still has more interesting shapes, but they can be incompatible with mods.
I might also make textures to go with my meshes (though you can really use every replacer with them), which make use of the new MGE XE PBR feature. But first I should really get the remaining meshes done.
