Hello i am using 3dsMax 22 and Vray . I started with arnold and i import step files ( inventor ) from various machines. Those machines have a brushed metal surface. Everytime the surface don´t look real, mostly like a gray surface.
I use an hdri environment.
Now i tried something different, i placed a simple cylinder with the same shader in my scene. This looks much better and the brushed surface appears. So i think there is a problem by importing the cad files into 3ds? What i am doing wrong?
Picture - left side imported machine, right simple cylinder.
