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 won't build, stays at 0%

I had a problem awhile ago trying to build light here. https://answers.unrealengine.com/questions/252785/i-cant-build-lighting-cashs-unreal.html That was solved and I thank this community. Now my problem is when I try to build light now, nothing is getting build. It's telling me that the light is being built, but it's not and it stays at 0% while the animation for the process is still going. I try to let it do it's thing and left then came back after 5 minutes, but nothing. I notice this started to happen right after I started to add foliage to my level.alt text

Update: it just took a really long time to build light. I guess my level was bigger than I thought.

How big is your level? Have you added a lightmass importance volume surrounding the playable area? Any errors from the swarm processes in the background?(check swarm controller) how detailed is the vegetation and the lighting/shadow quality on them?

I'd say its something of the above.

I would say my level is between small and medium. No, I have not added a lightmass or post processing yet. I want to add lighting last. I just need to build light to see how the light hits the bushes and trees I added and to see the shadows. How would I mess with the detail with the vegetation?
