Hi.
While testing an expansion to my mod, my character was able to walk through a vanilla mine epic wall and fall into the void. I can't add collision myself, so I have fixed this by adding collision planes along the length of the object and set their primitives to L_Stat. I checked the meshes in Nifskope and then checked every mine epic mesh. I found that none of the following have collision:
MineCEicorner01.nif, through to MineCEicorner04hole.nif, plus MineCEmid01.nif and MineCEceiling01.nif
The latter are not so important as they are roof parts, however I could well want to use them as cave epic floors (since there aren't any) and it would still look odd if a player fired a fireball up at an enemy and it went straight through the rock roof!
Thanks for reading this.
