[help]writing bsr and bmt files

i am able to replace a mesh and a texture of an old weapon or armor, etc
but if i want to make my own item i can get it to work

here is my process :
1. add new row into refObjCommon(copy paste an original weapon of the same class, and edit the things i need to change such as weapon degree, stats, and .bsr path, and icon path and the link to refItem
2. add item to RefItem and the id and link match,
3.i take a bsr of a similar weapon or item and edit it in a hex editor
example: original = shield_02 using this because it has two bms and that's what i need


here is what i changed it to

the skel file i didn't change it, same one as the original bow_02

the bmt, i edited the Shield_02 again because it defines the the .ddj for two meshes

and everything was uploaded to the correct directories.

as i far i can tell the problem is from either the bsr or the bmt because if rename and replace the meshes and textures with original ones it works.

if anyone's got any ideas please reply
