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"

How to fix this problem with light and textures?

When I edit my level in UE4 editor, there is no problem, it looks good. But, when I press play in editor, I can see an alert, that 'Lighting needs to be rebuild'. Ok, I build my game, and, unfortunately, after building level, by pressing "Play" in editor, I can see an alert "Lighting needs to be rebuilt". I don't know how to fix it. I hope you can help me with solution. Thanks a lot

The editor has the lighting of the level set to stationary by default, This means that the directional light inside your levels always needs to be "baked" into the map before hand. Under the "Modes" panel search for the "Lightmass Importance Volume". Drag this into your level and scale to fit the general playing area. Then under the toolbar click on the downward pointing arrow next to the "Build" button and select "Build Lighting Only". After lightmass has calculated the necessary values you should be able to play your level without the warning at the top.
