Help on Interior

[Conna3005]

Hello there.

I am working on the Set of my Interior in Octane Cinema 4d.

I still have Problems with the Shader of the Walls. A blanck RGB Spectrum does not look very good.
I am looking for a Displacment Map of a Raw Wallpaper. I need the right Settings for the IOR.

I am using the actual Version.

Could someone give me a Hint how to Texturice the Walls realistic ?
