Ok i just made some custom dragon armour, but it does not appear in game. Why would this happen?

Same thing happened here when I retextured imperial legion armor

All i did was change the stats, and placed there spawn in the IMD. but i dont think it likes where i put them (in the air)

Your big issue, from what I can understand, is this. You didn't remove the script from the armor. Checklist; you have to have completed all of these things.
1) Did you create new forms before you messed with the stats? (answer should be yes)
2) Did you select "NONE"in the Script chooser instead of the old one? (also yes)
3) Did you mess with anything that wasn't on the base armor attributes menu? (should be no)

i'm waiting for help with getting the game to see new textures, but for a different reason: when the new texture enters the screen, my game instantly crashes. my checklist for you is this:

1)creating new forms is not necessary, it should work anyway.
2)i have no idea about scripts.
3)new models need to have the following:
3.1)must have all the vertices in the mesh attached to bones or they don't appear in game.
3.2)as far as i can tell, must use existing textures. this was my problem, and talonboy93's as well. as soon as i find out how to fix this, i'll let you know!
3.3)after you edit a mesh, open it in nifskope, find the nitristrips, rclick and select mesh, then triangulate it.

1) Check...
2) ummm... Oh-No's we have a issue... there is no "NONE" script in the scripts.
3) Check (No)

Nvm i got it thanks guys!
