Custom armor causes ctd with weight slider

[Shoneah0Tokala]

Ok, so a basic rundown of my problem is this, I built a piece of armor at the _1 end of the scale and tested it in game, everything worked fine but there was no slider functionality, tried to scale the vertices manually and re export as _0, when I was poking around in nifscope I saw that the exact same armor had more vertices on the _0 which is bloody strange. anyway, I went in game and tested there no still no functioning weight slider (_1 mesh for nay weight). For my final attempt I tried using the So Much Morpher (SMM) utility to see what it would do (I've had problems with the SMM before where _0 and _1 were both fine but any intermediate was extremely messy.) and even though it all looks good nifscope it causes a ctd when I try to equip the armor and use "SHOWRACEMENU", go to the Appearance mage (dawnguard) or type "Player.setnpcweight 0" into the console. For good measure I attamped to change my weight via these methods then equip the armor and still got ctd at the point of equipping, Any help would be amazing and I will personally shake your hand (via the internet :teehee: )
