I have a simple model with a metal material that has some procedural noise to give it some realism. These noise irregularities of the material show up nicely in the material preview but not in my final render. I can’t figure out why. I’ve tried adjusting lighting and tweaking things in the compositor but still can’t make the details appear. I think I am missing something about how to work with lighting and cycles and bump maps. I have a basic 3 light setup with an hdri environment. In the Render Properties panel I’ve set the Color Management look to Medium Contrast. Below are two images for comparing. The top brick is where the material detail is lost in the rendered image. A link to download the file is also provided.
Some direction will be greatly appreciated.
Thanks for the help.
