hello, i know that octane has not a displacement option , but is there a way to make the stone wall more realistic ?
thanks.

You can use normal mapping. That still won't resolve the edges though.Still, it's better than bump.

do you mean to use the colored image instead of the floatimage option ?

Try nDo2 to generate norml map =)
the result is way better than playing with any bump =)

Or http://www.xnormal.net/1.aspx

There is also ShaderMap which has a free version and even the commercial version is cheap.

Or, depending on your modeling app, you could use a noise modifier (in MAX we have it) with the appropriate subdivision and make the wall look real.

there is a displacement modifier (Displace) where you can apply a bitmap, hence acting like displacement mapping

Can you please give some info about displacement modifier ?
I did not know about this ability of octane render.
A link or a small example.
Thanks.

Disp modifier is not available in octane, but in your modeling app, like 3ds max - you can adjust geometry there and after export just map diffuse and spec, but the surface will not be flat. This will grow your geometry count as seeing details you need quite hight subdivision amount, but if You have vRam resources available this might look really beautiful =)

..also You can always look around to buy few good maps in decent resolution to give You just enought details (those usualy have not only bump and diffuse, but also spec and even normal =) - they usaly don't cost so much ~ 5$ is enough to find something nice.

i was testing today a brick wall for one of my projects with the maps i've bought a while ago, pretty happy with outcome: take a look if it's interesting for You.

you could use your displacement map on a zbrush (or 3dsmax dispalcement modified) model and work with real polies.
