... one of the FX artists was on Corridor Digital's channel and said they were told to make massive changes from the originally planned fight to the final product. Marvel is kind of famous at this point for changing the location of scenes after they've been filmed, asking for lighting changes, asking for characters to be added/removed, etc.

I don't really blame Coogler or even the artists themselves for wonky CGI in this one or the first one-- it's pretty clearly a byproduct of Marvel truncating the time schedules, especially in pre-production, in order to release more content.
