Dear UE-team,
when running my project - indifferent if in UE4 editor or cooked or as application - I notice “flipbook rendering problems”.
I updated several rendering preferences for actor/BP but nothing helps. 
Any simple picture of FB is clear and sometimes it doesn’t flicker.
any idea how to fix or workaround?
Many thanks!
Best,
Tigger
Hi Tigger -
From your image it looks like it might be a MipMap Setting which is causing the issue. If you set the original Texture that you are using for your flipbook to the following:
(Open the Texture in the Texture Editor)
Level of Detail >> Mip Gen Settings: No Mipmaps
Compression >> Compression Settings: UserInterface2D
Let me know if this does not correct the issue for you.

Dear Eric,
seems to work. 
Is there any option I can use so that all imported PNG are automatically have this settings?
Many thanks so far.
Cheers,
Tigger
Hey Tigger -
Currently, no but we do have a feature request in to look at adding a more comprehensive option for importing textures, so it is on our radar.
Thank You
