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"

BUG - quality of the sun (lens flare, bloom) dissapear in game simulate

I have a scene with a strange bug - when I press simulate - sun appear just a white cicle without effects, and after stop it's still the same. But after project reboot - in editor all ok before press simulate - again and again.

I migrate this scene into blank project and create new level - EMPTY . I copy sun, skylight from this level to old scene (which I migrate), and on the old scene I delete anything.

please, see it: https://drive.google.com/open?id=0B8AB9z2m-RC1VldCLTI4NE1fLVE

On the EMPTY level all is ok - in Editor, in Simulate mode - sun is good. But if change map to ApartmentCUT (migrate map) and press simulate - sun ugly again. and if change level after it to EMPTY - sun ugly there too.

If restart project - all ok before press simulate on migrate level.

IF it's not a BUG, I very very appreciate explanation how this magic work.

Hi 6r0m,

In your level Blueprint you have a function called Scalability Settings. In this function you are setting your bloom quality to 0. This is removing your lens flare and bloom. Here is a screenshot of the node that is causing the issue. Either remove that from the function or set your bloom quality to a value above 0. alt text

Hope that helps,

Ed
