How do I set it up so that pieces that normally are loot can not be selected and grabbed?

I have a particular candlestick holder that I don't want the player picking up.

Thanks!

Is it a Misc item? You can try turning it into a static by creating a new static object, browsing to the model and use the model for your Misc item to make your new static. This sometimes works for me, but not always. There are other factors such as collision and Havock that might have to be accounted for though. I’ve made a lot of Misc Items by using static objects meshes, but only a few static objects using Misc item meshes. Hope this makes sense. You'll need to extract your meshes.bsa somewhere as well. I usually just extract my bsa files to another storage directory, and just copy over what I need when I need to do this. I've read this keeps from loading all the loose files when you play the game.

Also, as long as it’s a vanilla mesh and you don’t change the directory structure, you won’t need to upload the mesh with your mod if you release it. Just don’t change the directory.
