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"

Flickering Material after importing 4K Textures

Hi, I searched for this Issue but found nothing yet what helped me.

Today I created 4K Materials with Megascans Studio (I created a bunch of 2k Textures before, which worked pretty in UE 4.16), and imported it into my Project in 4.16.

And (I had it never before) after executing the textures in my Vertex & World Aligned Material (again which works fine with 2k textures from same software) the Material starts flickering on the used mesh.

I made a video. I hope you can help me with this.


Thank you :)

Product Version: UE 4.16

This is called "z-fighting" and happens when two identical meshes are exactly on the same spot.

Hi Luos, thx for your answer but in my case this is something other than "z-fighting". ^^

Now I dissolved it temporarily by creating a new material and use it without world alignment. The differences between my new material and the old: The new one hasn't: - worldaligned - 2 vertex blends instead of 3 - no additional powered vertex channels (falloff powers)
