I have a stupid question: How do I get a new static that I made (I actually retextured an existing mesh) into the CS to use? I've done this before, but it's been awhile, so now I can't remember how I did it! I searched for a basic tutorial, but couldn't find anything (maybe it's so easy it doesn't need one?).

In Nifskope, I took the ex_DAE_ruin_platform_01.nif and replaced the Daedric skin with a Hlaalu texture. I saved it off with a new name, and placed it in the Meshes folder. Now... how do I get it to show up?

Thanks in advance!

Just go to the tab you want to add the thing as, right click on an object and select new in the popup that appears. From there just fill in the blocks and buttons in the resulting window. Look at other IDs in that tab to get a basic idea of what to fill in.
