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"

Lighting build doesnt work above medium

Hello world of Unreal,

I am new to unreal engine, and i am trying to build lighting for a very simple scene that i have made for architectural visualization purposes. The scene is a simple house with a patio, no trees no grass. It was designed in Archicad then imported to 3ds max then to Unreal. All seems well. I have a stationary direct light and a stationary skylight. Nothing fancy. If i try to build lighting at medium its ok, it takes about 2-3 minutes to happen. However if i try to put production or high and build lighting it doesnt even want to start. The swarm kicks off, then stays for 10-20 seconds in 0% then just drops the job.

This is the log from the swarm agent:
