Using the Terramart graphic and the basic green tent .object and .frames files as templates, I made a quick thing just to see if I could figure out how to add an object.
I could not. Presemably I'm missing something very obvious but despite a bunch of different changes, I couldn't figure it out.
I just put it up on GitHub so that you could possibly see exactly what I'm missing.

The actual issue
In game, I can give myself the item, but when I try to place it, there is no visable "about to place" thing (I don't know the term). If I just go ahead and place it anyhow, it's completely invisible, BUT I can press E to sleep in it, as expected... even though nothing is visibly there.
Appreciate any help, thank you.
