Hello.
Your idea worked perfectly.
It was not necessary to delete the “DefaultEngine.ini” file.
First I tried putting all the default values of the editor. (And nothing happened)
Then I selected “Use Default” in the “Show” tab and then everything was fixed.
There is now no crash when using low scalability.
If I see that there are more problems I will delete the “DefaultEngine.ini” file too.
I will try to use short names in my files. I downloaded that specific texture that you see in the video from Quixel Megascans (that’s the name they gave it)… I’ll change them!!
Thank you so much for your help!! You saved my life!!!
