Yup! (still have not tested the model in game but the results in brawlbox are far better.)

Thank you for the help. 

While I do not know how to fix it i've had the same problem with playing smash infinite.

Hi i'm new to 3d modeling so i feel i'm doing something stupid but i figured i'd ask:
I've been using brawl box (the newest version) ctrl + e to extract a model in .dae form and import to blender and edit it (often sculpt mode) but when i replace the model with the .pac or .pcs file then i get a very bad result. any ideas?
(I would post a pic cept I dunno how to)
