Hey there! I used this Obito's mask in Unreal Engine 5 scene. But i really liked the result. I put to .rar several file. It makes your job easier. 1) Mask FBX with square and triangle topoligy. (2 file) 2) Substance file. You can export from it any tuxtur you want. But i forget to structur layers name in the scene. Sorry for that :) 3) And i put maps from HP. I bakes it in Marmoset.
You can look to Marmoset preview. You will see all maps and wireframe.
Mask is not GR!!!! Need retopology
