Hey everyone, I am fairly new to the modding scene. I know my way around Frosty and the SWBFII files, but I wanted to know how to delete parts of a certain class of a certain skin, i.e.: a 501st Heavy's backpack/bag/shoulder accessories/etc. I understand I have to change something in the dccb of the particular Phase 2 501st legion. Does anyone have a walkthrough of how to do this without breaking anything?
