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"

4.11.1 Arrow component causing rendering issues

A few rendering / post-process issues have occurred in the latest build of out game and I think rendering the arrow component (of a blueprint) in game has been the cause.

With the arrow component set to visible in game the scene's Ambient Occlusion disappears, the Screen Space Reflections become more powerful and the the Bloom intensifies. With the arrow component set to hidden in game the issues do not occur.

The arrow component was being used on a blueprint actor with a projectile movement that is functioning as a grenade. The arrow was being used to test/debug the rotation and direction of the actor. This actor is spawned on a button press and the rendering issues only exist during it's lifetime.

This issue is far from game breaking, but did cause us plenty of confusion whilst trying to test the grenade blueprints.

Attached below should be:

  • an image of the Blueprint Actor,

  • an image of the correct rendering,

  • an image of the correct rendering with Screen Space Reflections,

  • an image of the resulting incorrect rendering,

  • an image of the resulting incorrect rendering with Screen Space Relections

Hi Jules,

Thank you for the detailed repro steps and explanation. I was able to see this in 4.11 and setup a test project looking specifically at the three Post Process issues you called out. These look to have been resolved on our internal build of 4.12. Look for these fixes in a future release.

Thank you!

Tim
