I'm having some problems with setting FRN references and making them show in the CS within Nifskope. For some reason, either I can show the sitting reference to assign to the furniture or see the mesh but no entry vector. I did it once and took a picture in game with a character sitting in this mesh but I can't remember how I did it. :facepalm: Since then, I've resculpted the mesh and can't set it to a furniture piece. Can anyone give me an idea on what I'm doing wrong?

In the following picture, you'll notice I branch copied the appropriate blocks and then adjusted the entry points and orientation.

I see at block list that you have two NiNodes on the same first level. And at this level there can be only one NiNode (0), everything else outside of this NiNode is omitted by game's engine.
To fix this just select NiNode (4), copy it to clipboard (ctrl+c) then select main NiNode (0) and paste content from clipboard (ctrl+v), then select that NiNode (4) and delete it. Content of your NiNode (4) must be as child to main NiNode (0).

Thank you Trollf, that was it. I overlooked the second ninode.
