Struggling through learning UE from scratch, and this is my first time posting here as I am running out of things to try. The good old Google search isn’t quite cutting it this time I’m afraid.
So, basically, I have loaded a map from an asset pack I have used before, and previously it renders great and all the textures are high quality and very realistic. For some reason, with a fresh install of UE5 and a brand new FP game project, every single texture is loading at 64x64 even though they are 2K textures. It’s driving me mad, as I have changed the engine scalability settings from High, to Epic end even Cinematic and it makes no difference.
I also changed the texture settings to Epic, and again, no different. One thing I did notice was that what I make the texture setting change from Epic to Low and then back to Epic, it flashes up a high quality image for a very brief time and then reverts to a blurry 1980s style blocky mess.
What other settings can I look at to see if they have an affect on overriding this. Note I have not changed any individual texture settings. Also, I tried deleing the project file and recreating it from scratch, and the same thing happened. So I am wondering if something in my engine settings has become set (maybe by me messing around) that forces them all to the lowest quality. I am running UE 5.0.2.
Any suggestions or help would be gratefully received.
Finally… I figured this out after weeks/months since the issue happened again. Between then and now I have learned a lot about the Engine so bug fixing methodically and checking settings that I now understand better paid off. So, while the outcome was 64x64 textures and everything looked crap, it was nothing at all to do with shaders, or textures, or MIPs or LODs or Virtual Streaming, etc.
In my Engine settings, under General, the location of my derived data caches was set to a drive letter that didn’t exist. I had a portable SSD that I was using, which failed, then my new one created a new letter for the backup to be restored. The project loaded just fine, but the hardcoded path to the DDC locations was all still pointing to the old SSD. As soon as I fixed it and restarted the Engine, everything started working again.
Maybe this will help anyone else with this really weird and frustrating problem.
Thank you so much, you’ve taken a big headache away from me!
Just to add some more info, the path in UE5 for the derived data cache is in “Editor Preferences / General / Global”.
J’ai upgrader mon pc spécialement pour faire de la 3d ( gpu , ram et SSD ) et depuis 1 mois je n’ai rien fait car j’était complètement bloqué avec ce problème, j’avais presque laisser tomber , j’avais tout essayer changer les paramètre LOD , Mip Map , streaming pool…
votre solution à exactement solutionner mon problème
j’ajoute des mots clef pour aider d’autre a tomber sur ce post : Blurry texture, texture bad quality, quixel bridge texture pixelised , Mip map generation issue , Fix bad texture
