Hi,
I have a problem with my project after is transferred on my iPad Mini Retina. On my ue4 editor everything looks fine but when i pack it for IOS I have very dirty textures, especially on walls. My resolution for every wall is 1024px. I know that iPad compress the textures but I want to try to clean them.
!
In my scene I have: Static directional ligt, Static skylight, static ies profiles, stationary and static spot lights and indirect spot light(stationary) outside the windows.
You will need to change the texture compression from 0 to 2 or more (up to 4) in the Render settings for the project. We are looking in to adding a way to specify the compression for different texture types in a future release.

I can’t find it… Did you mean in the project settings, rendering section? Because there is no texture compression…
still don’t know where to change parameters for texture compression 
please help!
thanks
Hey ,
I believe the texture settings he is mentioning are dealing with the console commands and variables. We have some documentation on the ‘Engine Scalability’ and there is a section that deals directly with the overall texture quality of your project.
Texture Quality
Have a look at this documentation page for more information as well.
Let me know if you still need help.
Cheers,
Sry for my late answer but I’m glad to inform you that I did it! 
If anybody is interested in the same thing it is in project settings>cooker>PVRTC compression. Just set it up to higher number and it will look better. But it increases the time for packing a lot!
Thanks everyone!
