My MipMap artifacts when set to level 5

I’m constantly getting this bug in the mipmap generation.
Is there any work around? Is there a way to bypass a selected mipmap?
In this case only mipmap level 5 has it.

Hi fabianoberlim,

Can you please let us know what graphics card you have, and which driver version you are on?


Hi ,

The card is Radeon HD 7990 and Catalyst version 13.12.
The problem disappear from now, but sometimes it appear again. It seems hard to diagnose.


I have noticed that issue only 5th mipmap, using HD7970 Catalyst 13.12.


Thank you for your patience, is this still occurring in 4.1? We made some changes in rendering and it may have affected this issue. Please let me know if this is rendering differently.

The problem is still occurring in 4.1, but if I open UE4 again, it disappear. So I don’t think it is a big issue, since it will not appear in the game.
