I checked ingame, that's actually how I realized I had no collision. The meshes I put together each have collision individually (checked that ingame) but in my nif, only the stool that has it's own 'root' white box around it had collision.
No idea how I got to that result...
I used the 'root' collision of a doorjamb on my tent's entrance and that also added collision. I guess I cal rebuilt my 4 walls around the tent like that. I'll try again tomorrow.
EDIT: It's now tomorrow! I've statrted building my camp from scratch. I started with the tent, checked it had collision, then added the clothes, which also still have collision! What can I say, new day new rules...
I don't know what I did the first time round... Oh well, I'll keep going at my snailpace and add bits one by one, see if all those bits have collision.
Arff, I meant to edit my previous post, not reply to myself...
A proper edit this time...
I've rebuilt my mesh and it's fine BUT it loses all collision when I use the PlaceAtPC function (via script and dialogue) to well, place it in world. Any idea why it's like that? are work around it?
The good news is, it's not a mesh problem...
