Back in my Brawl modding days, I made a Brawl-styled Masked Dedede model import. Now, I've finally updated that model for Smash 4! It's about time I got this one finished, considering I started working on it over a month ago!
The model still has a few issues (such as partially messed up smoothing groups and some odd warping on some of the normal maps,) and it currently lacks facial expressions (mostly for the eyes,) but I have at least fixed all of the problems that kept me from releasing this.
As is usual for my imports, this mod includes a Metal model, along with all 4 of the "main" UI images, and a name tag too!
As of October 7th, 2016, this mod does come with altered models for Dedede's Jet Hammer Down Special (and his Bomb Hammer Final Smash.) However, there's currently no way to do one-slot replacements for those, so using these models will make them appear for all of Dedede's costumes.
If you notice any issues that weren't already mentioned in this description, feel free to let me know. And make sure to provide as much information as possible (since I can't really fix a problem if I don't truly know what's causing the problem.)
Finally, I don't do mod requests. I prefer importing models that I want to import, so please do not ask me to make any specific model imports for you.
