So we are still testing some things but I wanted to let you know of a fix we found earlier in the testing process so at least you can get back up and working. Create a new Blank Project with No Starter Content, let the engine open it and then immediately close. Copy all contents from the Original Project’s Content folder (Content folder only not the uproject file or the saved or intermediate folders) and place it into the new project’s content folder. Open the new project again and from the content browser open your main map. Re-enable the Distance Field Ray Trace and restart the editor and you main map.
You should be back up and running again. We will continue to diagnosis the visual banding and let you know if we find a more directed solution.
Thanks for the fix it worked when I loaded it the first time.
However opening the project today the problem appeared back, and I haven’t touched anything except the character controller since.
Ok, try the fix again, but be very precise about everything you do from the moment it first opens to the moment it closes again and you reopen it. Hopefully the generated reproduction steps will allow me to achieve the same here and we can look into the exact cause.
Hey Eric, I’ve tried the fix out a few times and it works for the first 2 times the engine is running, after that it’s back to the original issue. I’m happy to work on my project even with the issue as long as long as I know it will be fixed eventually. Is there a more permanent solution yet?
Can you, as best as you can remember, tell me exact what you do in the two times you open the level before it opens with the original problem again? As much information as you can give me will help us try to narrow down a cause.
Sorry for the late reply, I recently changed internet service provider and it has taken longer than anticipated to set up.
After completing your solution I opened the level through the content browser, and then proceeded to make some blueprint changes. Clicked save all, and exited the project.
For the second time, I loaded up the project directly through the launcher and opened the level through the content browser, It immediately had the issue.
FYI, the only blueprint i changed was the character bp

I have put in a request for our engineers to investigate your project further. It is indeed a bug but it appears to be an edge case but we are tracking down the cause. For reference, UE-6247.
We were having a similar problem on our project where the banding was occurring on our meshes, particularly the landscape. We fixed it by looking in the Default.ini and discovered that under the " [/Script/Engine.Engine] " there was 2 values for the “NearClipPlane” setting, with the latter setting it to a value that was way too low.
Changing this second “NearClipPlane” value to 10 fixed our issue, but any value between 3.0 and 15.0 will probably work and not break anything.
