When I try to create a stainless steel material, it always renders out splotchy. Even with settings on Ultra. Am I missing something? Any tips?
Any tips for metals and stainless steel?

I've been wondering about that too. I keep tweaking the color and reflectivity in hopes of finding the right setting to avoid that. It seems to be a new-ish problem.

Well I just asked Ted in his post here Recently completed project in Philly
his stainless looks pretty good in his kitchen scene. I am wondering if he using an RTX card?

Noisy metals have been a problem for quite a while see this thread: Noisy blurry metals - better sampling possible? (2.5.2.)
I'm using a RTX card and I'm having the same problems.

... hi - to get any better idea, could you please share a screenshot of your "splotchy" resault and the used texture?

If you look closely at Ted's render - the splotchiness is still there.

Brushed/non glossy metals are one of the areas where raytracing falls short because the number of samples needed to resolve an image is just too many to compute in realtime. I believe the issue is related to the roughness value causing too much light to scatter. In Unreal, people overcome this by clamping it at a certain level, which artificially results in more glossy (or no) reflections, but solves the noisiness issue.
