For the radial menus, I followed a tutorial I found on discord. I can send a link to it in the morning. The textures were pretty easy actually. I got the designs from various different websites, include here. Once I had the design I wanted (like the hexbear logo) I opened it in krita and deleted the background. After that I import them to a pirate version of substance painter.

The outfit assets I'm using came with an awesome set of stock textures and a great spp file for them. The file had really good materials for the fabric texture, wrinkles, and dirt. So all I really had to do was slap the new designs onto the stock shirt texture, adjust the colors, and export to unity. The whole process takes less than 15 mins to do now that I know how.
