I'd read through the pdf before starting with my scene (I've probably misunderstood or assumed something incorrectly), my understanding is that I'd need to use a Float Image instead of just an Image for the bump map, and that I'd be using the Float Texture in the Power section of the bump parameters. Is this wrong?
Perhaps it's just a trick of the light (or a crap bump map!). I'm rendering it having inverted the bump map in photoshop so that the darker colours will now be the areas that are 'higher' than the lighter areas, and the render so far looks correct which is very weird!
I've just seen since inverting the texture manually there is a Boolean 'Invert' in the bump settings, I'm just wondering now if Octane does just handle bumps in the opposite way to other renderers? Thanks for all your help with this, much appreciated.
Low sample render rendered with inverted bump map, material settings and inverted bump map are attached.

Sorry about the mix up you are right the whole time i was thinking about Image and Floatimage not float texture....Float texture is just a slider.
Im not sure but could you check your floor normal also you could try using portal on that window if you are not using it by now.

Just checked the normal of the floor, and all was ok, I'll just have to chalk this up to being 3DS Max being weird as usual when it exports the mesh. Is there a way to check the normal within Octane incase it has flipped somehow during export / import?
For a portal I guess I'd have to update the obj with a plane outside of the window and make that a portal material?

Yes you need a plane outside or the way i do it is close the window whole with a Face/polygon then assign portal material to that polygon but the expected speed up in your render should be at least 30% in such a setup. What Rico_uk said will work as a test.

yup that test is a good idea, it was facing the right way... I'm just gonna chalk that one up to just being a weird object or material that I've made, everything else I've done using a bump works correctly, and for this one inverting the bump works fine, it's just a little weird 'under the hood'.
