BLM was...Antifa riots every night were not. The media seemed to just ignore them...maybe with the theory that they would stop if not getting covered. Millions in damage, many police officers hurt and hundreds of businesses impacted nightly. Go look for stories on all the businesses that left downtown Portland because of the riots and the lack of city leadership to address them. On top of homeless, crime and drugs...it's an absolute shit show.
Again, a quick google search shows thousands of articles that specifically tie antifa to the riots in Portland.
The media did not ignore it at all. If anything, I'd believe that tie-in with "antifa" is greatly exagerrated by the media, since it seems like the situation in Portland is better explained via the horrible police escalation that happened there and the fact that there's a variety of groups that jumped into the vacuum.
