'Two weeks' turned into a few months, but I started remaking the Lego model to allow you to change the colors.
This is a quick and early draft. This post is just for fun. It will be changed massively:
>the arms' UV maps are currently messed and would be a pain to do anything more than a basic color. I literally did them in a minute.
>the draft UV layout gives too much space to stuff that isn't important and not enough to the stuff like the face and shirt. In fact, in the end, the head and clothes may be split into two meshes, so you can have more detail on each. If you really want, I can experiment with having home-away kits be automatically put on the models.
>In the videos, the animation is messed, mainly the arms. This can be improved a little but I doubt it will ever be great, since the animations are made for humans with shoulders and thin chests and stuff.
Nevertheless, as you can see in the bottom left, the face can just be put on as a picture. Send me a face (or better yet, try and figure out the UVLayout.png and submit a full texture) and I'll show you what it looks like in-game.
Again, these were all rushed, it will be less nonsensical in the end and have actual labels. Don't put actual effort into a texture yet.
Bottom left: circle for top of head, rectangle for middle of head, circle for bottom of head
Bottom middle: shirt (top row is [bottom side, front, top side (right is forward on the top side)] then bottom row is [right side, left side, back side] )
Bottom right: leg-to-torso connector
Middle: their left leg then their right leg
Top left: hands
Rest of top: their left arm then their right arm
