I started learning how to mod about a month ago, having gotten my feet wet with Jaxonz Positioner and moving static objects around to customize my Lakeside Manor to fit my own wants and needs after not finding a home already made by another modder that felt 'right'. I have managed to figure out a lot of the more complex tasks in building a structure, but when I go to fill it with awesome things I would like to be able to have my own custom containers and such with their own nifs, instead of just manually placing them together in the Creation Kit.
From everything I have watched, seen, and read, making a custom nif mashup is one of the simplest things to do in the entire world (so far as modding is concerned), but whenever I take NifSkope and put two NiTriShape branches under a single BSFadeNode it looks GREAT in NifSkope, but is completely unable to load in the Creation Kit. I am getting the typical error where instead of showing the object it shows the red triangle with the white exclamation mark.
Just to note, I have unpacked all of the BSA, and the only mod I have installed right now is Alternate Start, other than that I have fully patched and DLC's Vanilla Skyrim.
I'm not looking to have someone do the work for me, I just would like to have some help figuring out where I am going wrong. Of all the places I have visited this site seems to be one of the best collections of knowledgeable modders that might have an idea of what's wrong.
