First time posting, not sure if this issue has been dealt with. I was just wondering if anyone has been able to successfully modify the collsion geometry. So far I've only been able to import solid objects, though I would like to have a building with no transition into the inside. I've spent quite a bit of time exporting from 3ds max with niftools as well as trying to modify the geometry in nifskope, but alas I've been unsuccessfull. If anyone has any advice it would be much appreciated, to me as well as all my fellow modders with this issue.

Thanks.

Here's a thread which discusses custom collision. I found that certain types can be made, but you have to jump through hoops. I've also heard there is a new app which can make concave collision (the kind that cannot be made with 3DSMax for Skyrim)... NifUtilits I think it is. There's a thread for it on the NifTools site, but I think it's buggy so you may not be willing to try it.

I've taken to finding similar Vanilla meshes and splicing over their collision, then moving in into the correct placement. It's kind of dramatic, but it works - and you only have to do it once per NIF. Another workaround is to use collision boxes (in the CK, then script them to be at the object if it moves)... but this requires MANY boxes for certain applications; such as a building with windows and doors, or a boat.

Thanks, I'll check it out. I appreciate the help.
