IS there anyway to be able to apply multiple textures in the mesh seen below? Since I need one for eyes, but will I need to map the Eye textures to the mesh in another program? And how could I get it to show in the Unity Editor and function properly? (I used Blender)
I’m not sure about Blender but all 3d modelling applications should do it in a similar way. In Blender, there should be the option to select faces and assign a material ID. Then you need to create a multi-material which can hold an array of materials. Each slot corresponds to one material ID. Applay that to your mesh. Export and Unity should automatically import the mesh and materials.
