Let me know if it works for you

Do you have a blend file? I'm just trying out both substance designer and painter.

This seems fairly complex? What is this trying to make? I just have Substance export the textures using the "PBR -Spec and Gloss from Metallic/Roughness" and then export the roughness maps from the Metalic Roughness config.

I use the metalic and roughness for painting in Substance.

Hi
Octane does not exactly work the way a standard PBR Metal Roughness shading does. So its a little tricky to get the octane viewport to match Substance viewport one to one.
Also you are ultimately creating your texture looks in substance and you would want those to translate to Octane as faithfully as you can.

As Octane does not have an add shader so its not simple enough to overlay your specular reflections honoring the bump and normals. It get a little trickier here...
and as you can see you also have to add the diffuse colour into the specular to get realistic metallic reflections in Octane to make it work.

You have to use the Metal/Rough preset in Substance export and normals should be opengl.

Hmm I see, to be fair I haven't tried using a substance file for metal. Mostly just skin and cloth and it seems to translate well. I used a tutorial for Octane C4D that seems to get good results but maybe an actual metal material would need your node graph.

In case other people are interested:

I haven't done much with metal as well. I did do this hammer but it's all painted and rusted so no metal.

I did this through standalone, not Blender. It was just a straight up plug in the texture, nothing fancy.

Nice.

Thanks, it's a start.
