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"

Texture Streaming in 4.14 and 4.15 seems to be much worse than in 4.13

Since upgrading our game from 4.13 to 4.14 some of our users reports problems with very blurry textures. Thats why we try to upgrade to 4.15 currently but in our tests the texture streaming doesn't seems to be better than in 4.14.

  • This occurs not when starting the game only after driving a long route with the vehicle.

  • We resaved all Levels in 4.15 and called "Build Texture Streaming" before

In 4.13 we had only small problems with texture streaming.

Hey user37337,

Have you attempted to use the texture streaming debugging console commands to figure out where/why your textures are not being streaming in properly?

Texture Streaming Configuration

Building Texture Streaming

Run through these tools and if you are still stuck, let me know.

Adjusting r.streamingpoolsize to + only work in editor not on built game. The built game will still come back with "texture streaming pool size over" error in red on the top left of screen, as well as low/bad streaming textures. I'm using 4.16.3

Hi NuHabitStudios

do you use World Origin Rebasing? Then maybe this can be your solution: Texture Streaming broken with World Origin Rebasing

Also, static meshes will cache the texture streaming resolution appropriate for whatever scale they had when the render state was last recreated. So if you rescale meshes, that can lead to problems. I just fell over that issue and saw your post while researching a solution:
