Super Smash Bros. Ultimate Ripping Project

[Essential]

I'm running into a weird issue in Blender where King K Rool's cape is rendering with what looks like weird polys. Also, all the metallic segments don't seem to light up and are rendering almost completely black. Anyone have any ideas on what might be causing this?

For the cape issue, there are 2 capes clipping I suggest to turn off the view on one of the two capes from at least how I experienced.
