Firehawk7171 made a great mesh for his Hiccup Armor mod, but the texture was lacking. This is my best attempt at retexturing it to look like it did in the movie. You will still need Firehawk7171's original mod, which you can download here.

Installation:
First, download and install HTTYD2 Hiccup's Armor
Next download the retexture. When you install it overwrite files when asked. The mod is now installed.
