For quite a while in the beginning when I first started using UE about 2.5 years ago, everything ran smoothly across multiple versions and many different projects. However, several months ago suddenly that came to an end and I started experiencing all kinds of small bugs that persist across 4 different versions of UE and numerous different projects. Issues include everything from Nanite visualization triangles view not working, to PCG graphs not updating when I move a spline point, and lots of other little things in-between.
The main question I have is, is there a way to essentially “reset” quite literally everything associated with Epic Games and Unreal Engine to bring it all back to the way it was the day I first installed everything? Since everything ran so well for so long, but then suddenly stopped running well across all versions and projects, I have to assume there’s something deep within the inner workings that controls all of UE regardless of version or project that “broke” at some point and I don’t know how to fix it. I’ve tried uninstalling and re-installing one of the versions and that didn’t work.
As far as I know, The only way to Reset Unreal Engine is to going to Launcher and there using Verify in Dropdown menu.
You could also update or downgrade your Graphics Cards Drivers
Also what hardware do you have? Because I have noticed unreal engine 5 becomes very unstable on Older Hardware even if it was working very smoothly on same Hardware 1-2 years.
Thanks a ton for the reply, I appreciate it. AMD Ryzen 9 5050X and 4070 ti are what I have (I’m not well-versed in computers, so if that’s not what you meant then my bad ) but I just upgraded my drivers the other day and the problems still exist. Before upgrading mine, I looked online at what people were saying about the newest upgrade and how UE was performing with it and it sounded overwhelmingly positive, so I think everything is fine on drivers side of things. But I haven’t removed the files from past upgrades, so I don’t know if that could affect things
I have similar but little Inferior Specs Hardware R7 5700x, 4070 with 64GB RAM and Unreal works Smoothly like Butter on my current PC. It’s definitely not Hardware Related (Unless you have Faced odd behavior in other Programs as well)
Do you Face any Crash or just internal Engine Bugs?
If crash, Can you Share Crash Logs?
If Internal Bugs, Can you Share Screenshots or Reproduce Steps soo that I can Confirm that it is only your Engine Bug not Global.
I have UE 5.2.1, 5.4.4, 5.5.0 (If you have any of these Engine Versions, You can share Reproducing Steps for these Engines)
My bad for the late reply, but no, no issues with crashes and no logs or anything. And there really isn’t any elaborate sequence of steps that’s causing these little bugs. If I open my project, without doing anything, the problems are already present; for example switching the view to nanite triangles, all that happens is the lit view gets quite a bit darker, ambient occlusion doesn’t work despite following all the steps in both material set-up and AO enabling, if I move a spline point on a PCG graph for my landscape, the plants don’t update, if I put a comment box around a set of nodes on the PCG graph, the comment boxes will be gone the next time I open the project, etc.
I also had the Dash plugin on a couple versions (I’ve since lost them because I un-installed a couple versions of UE and re-installed them to see if that would fix these issues, and I never re-installed Dash), but when I had Dash installed it was experiencing a bunch of different problems that nobody in any Dash tutorials ever had to deal with, so it seems I was the only one dealing with the kinds of bugs I was dealing with. And like I mentioned, I didn’t have to perform any steps prior to any of these issues arising, they’re present immediately after opening the project.
Does it Happen on Single Project or all New Template Projects as well?
also does Nanite Triangle Viewmode becomes completely Dark even after Having Nanite Meshes on Screen? and AO is Completely White and doesn’t show any Material AO even after Setting up?
Nanite viewmode is usually Pinchback if there is no Nanite Meshes in Scene.
Can you confirm these 2 things working or not?
Unfortunately I have never used PCG to Confirm what you might be Facing (although it seems like something I faced with Metasound Graphs).
Well surprisingly one of the projects has working nanite triangles and AO now, but the other projects I tried nanite triangles didn’t work, and that was after making sure there were nanite objects in the scene. Here are a couple screenshots of lit view and triangles view:
I tried the comment box again and again it didn’t work but I didn’t take any screenshots of that since it would’ve just been one image with a comment box around some nodes and an image without the box and I figured they wouldn’t be of any use.
And then all the issues with Dash still persist and I know I have run into other bugs that used to not be present prior to several months ago, I just can’t remember all of them.
I have never seen such Bugs in any version I have used.
Something is Definitely wrong with either Engine (Most Probably) or Project Files.
The only way I know to Identify is-
For Project Files, Delete .vs, Binary, DerivedDataCache, Intermediate, Platforms, Saved and .sln File in Project Root Directory.
For Engine, Go to launcher and Select Engine Dropdown Menu and Verify, If it Detects somethings or Download some Files then it might indicate that Files were Modified/Deleted etc.
Other then that I can’t guess why that kind Bugs you might be Facing even after Reinstalling Engine
The Last Resort might be to Install UE in another Drive/Directory with proper Firewall Access (If Installed in Network Drive) or maybe Downloading Source and Compiling from GitHub.
Also Unfortunately Unreal Team won’t Fix Bugs of older Engines, They only Fix for Latest Engine Version or Upcoming.
