There is a version on the Nexus but it has all of the bump mapping and such removed. Where is the original one?

Here you go.

THANK YOU!! I thought it was gone for sure!

'On The Rocks' is [censored]. People should be warned before using it. Mod changes the shape of the rocks which leads to all sorts of trouble: floating and hidden objects. It's one of the many [censored] mods done by modders who don't play this game anymore and rated high by others who don't play it either. Some days ago, i would have advised you to use 'CorrectUV_Rocks' instead, but it's the same [censored]. 'Meshes\f\Terrain_rock_WG_17.nif' hides the entrance of the 'Assarnud' cave, 'Meshes\f\Terrain_rock_AC_10.nif' makes the entrance to 'Nchardahrk' float. Most morrowind mods are utterly [censored]. If you want something to work, do it yourself.
