Octane for Blender, materials / textures don't render

Hi all,

I’m trying to use Octane for Blender to render a scene that I created using Eevie / Cycles. The materials render just fine in Eevie / Cycles, but they don’t render with the Octane engine! I just get a standard white material with no textures etc. Is there any way to get my scene to render with Octane for Blender without having to manually re-create the materials of over 200 objects that I have in the scene?
