So last time i created a base Char here

https://opengameart.org/content/low-poly-base-character

but i really disliked the textures. Then i saw the technique from following artist https://www.patreon.com/minionsart  and tryied to apply it to my self.

I used a 32x32 pixel Texture Gradient and streched the UV.

The Armor Parts on the model are removable you can see a 3D preview here

Feel free to use it for your game, it is not rigged.
