Before passing to Arnold I was a Mental Ray's user.
I remember there was a beautiful Autodesk Concrete shader,
that with no bitmap, I could have an effect like this:
There was an option to choose broom straight bump map and a weather map that
created these beautiful abstract "water waves" on the material, I repeat with no bitmap assigned.
How is possible to have an effect like this in Arnold?
I have to use the noise map as 3d bump map on a standard surface shader and play with the values?
I must apply to a ceramic tile floor.
Thanks for any answer...
Petros.
I personally did that years ago for autodesk (coded the whole adsk mat library). There're some noise and cellular procedurals together with some embeded bitmaps. You don't see them because they are wrapped into a mr phenomenon. I can't remember the details but you may have a look at the adsk_Mtl_Concrete.mi file into nvidia/mentalray/v2 3dsmax folder and try to replicate it.
