I'm rendering a glass bottle, and I'm using a small amount of Octane noise to break up the glass surface a tiny bit. I have set the projection of the glass material to cubic and it looks great.
I also want to use displacement to add the circle of ridges on the bottom of the bottle and the manufacturers dots and marks around the bottom sides. I've created a UV map and textures in photoshop for this purpose.
The problem is when I now use UV Mapping for the glass material, so the displacements work, I lose all the detail in my noise bump and the glass looks smooth.
What's the best strategy here to get both things working together?
Thanks for any help.
bump and displacement advice

Made a new glass mix material, piped the glass with the noise bump into Material 1, set the amount to 1. Piped the displacement psd and displacement node into the Displacement port of the mix material.
Applied Mix Material to bootle, and, same result - I get a nice displacement if I use UV projection, and nice noise bump if I use cubic, but I can't get both together.

no-one seems interested in my little problem! maybe a pic will help
on left is material with cubic projection, you can see how the noise breaks up the edges of my highlights on the glass
on right is same material set to UV projection, which works great for my bottle base details, but smooths my bump out and kills the details I'm after
the material is a mix material, using the same material with the noise bump in both slots, then the displacement is piped into the displacement slot of the mix material

Have you tried to map the bottle witn UVW and in the Bump channel modify the projection to Box and scale the bump as your needs?
Here it works with 3.06
