That seems to be a somewhat decent solution. Do you know about any guide/documentation about how to do this? The only one I found has the images no longer available. I have successfully created the static collection and tested its nif - that works fine. However, I have issues with copying the collision data to the nif file with my mesh. I have tried copying the branch that contains hkNPCollisionObject with no success. EDIT: Ok, I have just got the collision box working by copying the mesh to the SCOL nif. Now I just have to somehow make it "movable".
