A little "Texture-swapping" test. The body texture for Tails are the exact same as the one from Sonic Generations, but lighter. The eye texture from Sonic Forces are however different as the Generations' eye texture lacked some white pupils.

Rendered with Blender 2.8x's Eevee rendering engine.
Miles "Tails" Prower from Sonic the Hedgehog© and is the property of SEGA©.
Model by ApocHedgie. Textures from Sonic Forces.
Converted to .smd via "Crowbar" tool for use in Blender. I own nothing.
