Weird looks around Mannequin

Hi,
I have been using Unreal for a while (still a noobie) but I’ve always had these issues around some characters and on specific camera angles. How can I get rid of them?
I did some research around this and I’ve seen people say it’s an antialiasing issue. I tried changing the AA type but still no luck. I feel like the solution to this is silly but I can’t seem to figure it out.

is this appearing when you launch the game/ hit simulate?
could it be the Taa upsampling?!
