Viewport textures do not match Octane live viewer

[Jur]

I have this 2D facial rig and I've been a little stuck transferring it to work properly with Octane. The rig used the default Cinema 4D materials, but since the alpha map did not render properly in Octane, I transferred it to Octane materials. This worked, but here lies the problem;

My viewport is now completely different from my Octane live viewer. It renders correctly in Octane, but no longer displays the correct textures in my viewport and gives a white texture instead. I posted a picture below with the comparison, in a nutshell; I need the Octane live viewer to match my Cinema 4D viewport - it uses the diffuse and opacity channels. Can someone please explain to me how to fix this? It is pretty urgent.

Since Octane materials are 3rd party there's not much possibilites to work as Standard materials in Viewport. Anyway sharing a sample scene will help you, but not guaranteed to work as you imagine.
