just word of advice you should really try smoothing it out more cause even my nicely modeled h3 marine helmet wasnt smooth enough for pep, so it created alot of unnessicary folds which in turn would make the assembly process disaterous, so best thing you can do is export it view it in pep see where all the un needed folds are and try to adjust the model in ur program slightly so it eliminates the extra folds i had to do that with my models to make them more pep friendly
