https://drive.google.com/file/d/1z-vz1a97oQDZq7CMZUEsCfgDLbg3Onl-/view?usp=sharing**This is my version of Captain Britain's cut MUA1 Ultimate skin.
*I started with Genis-Vell's body model (thanks to Jayglass for the idea) and Hawkeye Ultimate's head model (using UltimateMegaMagnus's source file and texture) and extensively modified them (with help from BaconWizard17) to get the official texture (which artist Jason Harlow posted on his website along with a screenshot of the finished model) to fit as well as possible on the model.
-I also reshaped Hawkeye Ultimate's head to look as close as possible to Captain Britain's headshape in the screenshot.
-Due to massive unfixable issues, I removed all the stripes from his feet except the ones on top of them and repainted the entire foot.
-I added in the back of the neck, which was missing from the official texture.
-I remade and repainted the gloves by using Genis-Vell's Wii texture as a starting point.
-I made various other modifications to the official texture to get it to fit the model, to fix issues with it, and to make it look better.
-I've made the textures DXT1 because making them PNG8 badly ruined the texture.
-I've hex edited the MUA1 version for Captain Britain's MUA1 mods.
*I've done 2 sets of huds and character select portraits:
-One I made by taking a screenshot of the model and using part of a textless cover of Marvel Tales: Captain Britain Vol 1 1 by In-Hyuk Lee for the XML2 versions.
-The other I made using a cutout of the only official MUA1 art of Captain Britain we have, which is his appearance in one of the MUA1 epilogues.
