Models in Unreal Engine Suddenly Appearing Low Quality Despite No Changes

[IdrisKhan]

I’m experiencing a perplexing issue with the quality of my models in Unreal Engine. My models used to look very high quality, but recently they have suddenly degraded to a very low quality, as shown in the images below. I haven’t made any intentional changes to the settings or project that should have caused this.
This is what the Mesh looked like before:

This is how it looks now:

It appears that the materials are causing the models to look bad.

Troubleshooting Steps Taken:

1. Disabled texture streaming.
2. Verified that the issue persists even in the shipped (release) build.
3. Reverted to previous commits where the models appeared correctly, but the problem persists.

Any advice or insights would be greatly appreciated. I’m at a loss and would be grateful for any help in diagnosing and resolving this issue.

You have to get rid of this error

Restarting the editor will do it, but you can also increase the streaming poolsize ( if you have more VRAM ) with the command

r.Streaming.PoolSize N

where N is the new size.

I updated unreal and it fixed the problem…

When you’re out of video memory there’s no point increasing the texture pool. If anything reducing it would be beneficial. Unread doesn’t unload things in the editor so a restart is the right call when you see that message, reducing pool is the next step if you see it all the time in short sessions.

Disabling texture streaming will just make the out of memory issue worse. Keep an eye on that warning and restart when needed. If you have a ton of high Res textures it might be time to upgrade your GPU or reduce texture sizes.

The editor default is 1G. Most GPU have more than that, so increasing the pool is a good first port of call
