Texture baking of maps for remeshed objects?

[pegot]

How do I bake the Roughness & Metallic maps of a high poly mesh onto the new UV’s of a lower re-topologized object? Blender Cycles can do this as per the below video. Can I do
this in Octane Blender? And if so, how?

If I understand what you are asking, you can do it via Blender itself instead of through Octane. If you transfer the high poly object's UVs to the low poly mesh you should be able to bake the material on the high poly object then copy it right onto the lower poly mesh.

Yes I have been doing it through Blender but for some reason when I try to bake the Roughness map it is coming out just black and white. So I thought I would see if Octane can do it. Not a huge issue I can always paint in a roughness map in Substance Painter or generate one from the diffuse map in Substance Sampler (and even Designer I think).
