How can I add a realistic metallic texture to this node setup?

So here is my node setup for a model i want to animate. Ive added a diffuse,bump, and specular map already but i have one last metallic texture i want to add but there are no tutorials online to help me add it, much less with this setup. Please let me know how i can do this.

• What do you expect it to look like? Please use the edit link at the bottom of your question (i.stack.imgur.com/lXFuK.png) and add areference image that illustrates what you are expecting to get. – cegaton May 21 '18 at 18:04
• Is this a ripped character from Fortnite: epicgames.com/fortnite/en-US/patch-notes/v4-1, lezisell.deviantart.com/art/Fortnite-Thanos-XPS-ONLY-744161135?? Uncool.. – Jaroslav Jerryno Novotny May 21 '18 at 18:47
• @JaroslavJerrynoNovotny Im curious why is this UNCOOL? I dont play that game, Is this a model that was not supposed to be given away? – icYou520 May 21 '18 at 22:53
• @icYou520 pretty sure it was not supposed to be given away and was just ripped from the game - else it would be available to download from the unreal asset store (like the free characters from Paragon that was discontinued). Don't tell me you don't know why theft is uncool.. – Jaroslav Jerryno Novotny May 22 '18 at 7:48
• @icYou520 aah, I see now, I didn't know you didn't know, sorry:) Yeah, some people go great lengths to unpack models from games. Fortunately its almost always for non-profit use or game mods. But some people put them in portfolios claiming as own or there is even porn made with them.. Worst is when part of the game is cloned and modified for chinese markets and makes profit there. – Jaroslav Jerryno Novotny May 22 '18 at 15:04

To give credit where it is due, I obtained everything I use in this demonstration from here: https://pr0f3550rz00m.deviantart.com/art/Thanos-Fortnite-3D-Model-744104114

Now, for each individual mesh piece: (make sure you're in object mode) Select the mesh, press SPACE and search for weighted normals and hit ENTER. Then, with the mesh still selected press SPACE again and search for Clear Custom Split Normals Data and then hit ENTER

Note do not apply the split normals to his face, as it will cause hard edges on an organic surface, which we do not want. After applying that to mesh, we can begin the node setup!

Also you'll need to remove all of the parts which relate to his skin, as they should not be treated as hard surface objects either.

For point of reference, the metalness and specularity maps contain information as follows:

R = Ambient Occlusion

G = Unknown

B = Roughness/ Metalness/ Emission

A = No alpha channels are included

Helmet and Torso Node Setup

This is the general setup for the helmet and the torso piece, however; the gauntlet and face have an extra part to them as they both seem to contain a part that emits light.

Make sure that textures not affecting the colour are set to non-colour data

Face Node Setup

You could just use the original diffuse map to control the emission value, I just happened to make a duplicate of it in this example.

Gauntlet Node Setup

This time I just use the original diffuse map for the colour input.

Just in case it isn't clear from the image, the blue channel from the metallic map is controlling the factorial of the mix node.

And here is an example of the final result:

Hope this helps.

• "To give credit where it is due" - pls don't give credit to people that steal assets from games.. Giving credit to the thief does not make your usage of the asset ok. – Jaroslav Jerryno Novotny May 22 '18 at 8:16
• Fair statement and I understand that taking people's hard work in modelling and texturing isn't the most ethical thing to do, but similarly; the time and effort that goes into creating code that can grab the various data associated with models requires a similar amount of effort and time. Not to mention having to create a system to dump the files and then decrypt the files specific to the game's engine, so that standard programs can read them. Put simply, I gave credit from where I obtained the assets from, showing that I was not the one who put the effort into extracting it. – masterj2001 May 22 '18 at 8:27
