I have a set of shaders which under Carrara's own render look quite good, I can get reflections if I use an HDRI for lighting, but under Octane they look flat and dull, I have tried changing many things in many different parts of the shader after I convert it to a Octane material and I just seem to be making matters worse

Should I cheat and use a jpeg in the reflection channel before I convert it, or is there something I am over looking, more than likely is.
Thats the main issue when I use something new, everything I learnt about previously goes out the window
