I exported my texture from the substance painter in UE4 format, then made a simple material and pasted it on my object. In the editing interface of the object, the texture is normal, but after dragging it into the world scene, he It becomes as if there is a mosaic filter, what is going on?
· In Editing interface:
· In the world scene:
I think this is the problem
Can you try a higher setting?
I have adjusted the overall image quality to Epic level, but when these objects are closer to me, especially when the camera is almost close to them, they still appear mosaic like, but when I am slightly further away, they seem to be normal again ：(
In Cinematic , every is all right , but that model is too laggy TAT .
And in low image quality mode, some materials related to terrain are normal, but others appear mosaic like . The size of them are same . This is really confusing.
Well, the engine is doing it’s job, and downsampling textures when you tell it to 
Something you might try, is working in Epic mode, but turn off real-time. There’s a menu here
Then, the engine will only use the GPU when you move the camera, or change material params. It might be a happy compromise?
Unfortunately, I’m working on my game coursework and turning off real-time calculations will exacerbate my problems 
The cases on the Internet are basically blurred because of the texture pool, not mosaicization, which is really uncomfortable
