Getting some random problems since 5.4.1

Development Getting Started & Setup

Greetings everyone !

I hope I’m posting this in the right section of the forums, I’m in a bit of a pinch and not too sure how to solve it.

Last month I was working hard on a project (migrated it to 5.4 without any issue) and unfortunately had some problems with my other business. Couldn’t really get back on unreal before this week.
Had to upgrade to 5.4.1 and also upgrade a few purchased assets from the marketplaces as well.

I was surprised when I went back in as half of my textures didn’t ‘load’ properly (or that what I thought). Most of the stuff I have here is free assets to learn the ropes; but there’s also some paid ones that did have the problem. But this seem to be a bit random. Some textures that were before in 4k were now in 16x16 or 64x64.

Managed to narrow the problem to the compression of the texture and found a workaround, setting the settings to UserInterface2D (from Default (DXT1/5, BC1/3 on DX11)), or ticking the box for “Compress Without Alpha’ or ‘Editor Defer Compression” would get me the texture back in the correct size. (But I’m also not 300% sure of what those option does)

I can also see some strange LOD with the texture that seemed at what point to act in reverse, getting lower res as I was getting closer to it. (this is a feeling, I have little knowledge in unreal and I’m trying my best to understand in what hole my feet had been sucked into)

I’ve tried my luck with really large map, so I’m aware about the Texture streaming pool, and I’ve never had to update it in this scene. Trying to raise it do nothing at all.

If I restore editor to default, launch a third person new project and import the model, I’m still having this issue.

I am also experiencing very strange stutter that seem to move my FPS from 160+ to 50 constantly that I had no prior to the update. But this FPS problem dosen’t seem to kick in a new project so I guess this is a different matter.

Earlier I bumped into that notification, unsure of what it does. Couldn’t really find anything related to it that would help my problem.

Getting an earlier archive of my project into 5.4.1 would result in the same texture problem.

I’m in the process of trying my luck on another computer.

So any helping hand or kick would be so much appreciated, I’ve been running circle for the past 2 days and I’m almost out of medicine for headache

I have this texture problem, textures that are clearly 4K show as being 64x64 when you open them. Changing to ‘sharpen 0’ fixes it, but why should I have to do that!?

:smiley:

The LOD problem you’re having is the same thing, there is just no large texture to load as you approach.

I’m pretty sure it’s something to do with mips not operating correctly. If I’m some distance from a model, and I look at the in the texture editor, it shows as 64x64, but as I move closer, when I go back to the texture editor, it’s zoomed in further. It should always show at the correct size!

Quite irritating…

Yes, it seems like a bug or an overall change to the default setting. You can fix it for now by opening the texture and setting the “Mip Gen Setting” to “Sharpen0”. It looks like a bug starting from version 5.4 or a major change.

If you’d like to change all textures in one click, you can select all textures and use the property matrix :wink:

Greetings @4ias

Welcome to the Unreal Engine Forum. As Clock mentioned, changing your to ‘Sharpen 0’ will remedy the problem. I’ve saw this reported on other threads as well. Thank you for the info and I hope that resolves the problem!
