Do you think you could send me a file with all of the textures? All of the base color textures are included, but the normal and MRA maps are missing. My Discord tag is heccertim#9040.
Wait, SAB64 and matthew250 made a Matter model as well? That's a strange coincidence. Neither of us copied the other, as you can easily tell that the models are completely different. That's interesting, though.
You might have to manually apply the materials. The only materials that you will need to apply are the ones named body, eye, pupil, and outline. You will have to apply these materials directly to the mesh components.
