Original

Comes with 13 textures of which 6 you will need to replace.

Node 1 : PBR Texture (RGBA)

R - Sub-Surface Scattering (Use Black Image)
G - Roughness Texture
B - Ambient Occlusion
A - Use a full white grayscale map or fully opaque

INFO

For the Sub-Surface Scattering, use a black grayscale map.

Node 5 : Bump Map

This is technically a micro-normal texture but for our purposes we will just replace this with a blank normal texture.

Node 6 : Normal Texture

Node 8 : Emissive Texture

If you do not have an emissive use a blank PNG instead.

Node 9 : Bump Map

Same as Node 5, replace with a blank normal texture.

Node 10 : Color texture for your model

Other Nodes: (2, 3, 4, 7, 11, 12, 13)

Fill with a blank png. Using a 128 x 128 pixel empty png gives the best results. Using textures with a lower resolution than 128px has been seen to cause issues.
