Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

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. alt text

Hi fabianoberlim,

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

Thanks

Hi Stephen,

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.

Thanks

Hi,

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.

Thanks!

Alexander

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.

Thanks!
