I have been having this same issue for a couple of months and found the solution here so wanted to share:
It turns out to be in Near Clipping Value in Project Settings. In my (shared) project it was set to 0.1. Increasing it up to a value of 5.0 did the trick for me and renders from MRQ are looking as expected now.
Nothing to do with the Groom asset or Console Commands which is where I was spending a lot of time.
Hopefully this solves yours and other people having this issue in the future.
