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"

Hi RuiShi -

Can you post your Machine ID which can be found in the Crash Reporter that pops up when you are asked to submit your crash? (Also make sure that you have in fact submitted your crash.)

To clear a few quick possibilities if you open the Swarm Agent outside of the editor (found at \Engine\Binaries\DotNET\SwarmAgent.exe) you can clean and validate your Cache which will clear some HDD space which more often then not is the reason some crashes can occur, you simply run out of HDD space.

If you are using a GitHub version of the engine make sure that you have compiled the engine on Development Win64 first which will build the SwarmAgent Lightmass settings that are needed to build lighting.

Finally test building lights in a sample project, like first person Shooter. Make sure to create from a New Project window and not try to upgrade a former template.

Thank You

Eric Ketchum
