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"

Directional Light and shadow broken in latest versions

Hi, I just found a very weird behavior with the light system that was not present in any previous version, seems like a big bug.

My procedure to check this out is simple: create a blank scene. Add a box to see the shadows of the box.

In UE4.x (till 4.19) you can move, rotate, change the type or add any other directional light. In UE4.21 and 4.22 by rotating or changing the light type (to movable for instance) makes the shadows not to display correctly anymore and the whole light system starts to behave very weirdly.

in the next picture I I just rotate the light, this is the result I get

Please let me know if someone else is having this problem. Im using windows 10 on a racerblade with Nvidia 1070 video card.

Thank you

Product Version: UE 4.21

I'm getting weird shadow issues too on 4.21.2. I can get a build to display the shadows, especially the ambient occlusion. but as soon as I touch my mouse to move, the shadows go away. If I package the project I can get see the intended lighting.

I have a Dell laptop with Nvidia M3000. I thought it was something with my system.
