I also needs some help with a mesh that needs some Nifskope care. The case is the following: I started editing some meshes to make holes in them for the Leviathan Domain, however on export they lost the reflectiveness of the windows, while understandable it is really annoying because so far, no matter if I copy the entire branch over to that NiTriShape of the model it still doesn't get the reflection o_O If anyone is willing to look at it, I can send the two meshes, the edited and the original so whoever picks it up can make an educated guess and perhaps teach me how to fix it myself.
Cheers
