Things fade in from black when turning corners?

So I have this little project going on and recently upgraded from version 8.3 to 10.4 and now I have this problem. Basically whenever some things come into view from behind an object they are black at first but then fade in. You can see what I mean (on the red parts) in this gif:

It should be noted I didn’t have this problem at all back in 8.3. It’s very undesirable to me because it’s so distracting and unpleasing visually. I was wondering if it maybe had something to do with LOD or occlusion, but I’m not sure at all. There might be some very obvious fix to this that I’m missing, but know that I am still new to the program. If someone here knows what’s going on and can tell me how to fix it, then please help a brother out! Any responses will be greatly appreciated.

Thank you in advance.

Bump. Still have this problem to this day. Whenever something passes the glowing edges of the platforms on the map it’s like it leaves a print on it in my view that fades away. If someone knows how to help then please do!

first, obviously try building the lighting and see if that works. what are your render settings set to? if theyre not all the way up go to the top toolbar and choose settings> then graphics (or something like that) then set all of the settings up to epic. i had an issue similar to this and that what fixed it for me

Huh, well firstly thank you so much for your response. I think I actually have both of those things going on already, but it still happens for some reason. Thanks for the help though.
