Unreal 4 Mipmap or Unreal Bug?

GhostBlades · Nov 2014

Anyone ever have this situation where sometimes some objects (in most cases a rigged object) starts getting some pretty bad texture quality as you step back a few steps and the closer you get the better it is...then once you go into the content browser and check the texture map - the problem goes away? I managed to even see it in the material for the object

Is there a fix for this? is this a mipmap issue? Just to re-iterate it seems to mostly happen on rigged objects (skelmeshes)

It's the texture streaming. You got to select "Never Stream" in the texture properties to prevent this behaviour.

Oh I see - thanks

What exactly is the purpose of texture streaming? is it a performance thing?

Texture streaming means that the engine unloads unnecessary mip levels of the texture, reducing GPU memory usage. Engine somehow calculates how big the screen space of some texture is (plus other factors), and then loads the appropriate mip level into GPU memory.
