I dont get matching bonus from light armor, I have a hood I mod my self, do I need to add something to it? a script or something?

Does your hood have the Light Armor keyword? If it doesn't, then add it, should work

Keyword?

On the right side of the Armor-form, there's a list with keywords, make sure the keyword 'ArmorLight' is on there.
If it's not, right click in that list, click Add... and choose 'ArmorLight'.

Thanks found it and it works, tho wasent the hood, was the boots doh..
