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"

Lightmass Portal - What is it?

What exactly is a lightmass portal and how is it used? I've done a quick google and I can't find much about it.

Thank you!

Hi gpb1989,

The release notes for 4.11 include some details about this new feature: https://docs.unrealengine.com/latest/INT/Support/Builds/ReleaseNotes/2016/4_11/index.html

This should help you understand and get started using them with your light builds.

Sorry, but I still don't get one thing: do I still need a lightmass importance volume or I have to replace volumes with portals? I'm using ue4 4.16 THX

You still use a Lightmass Importance Volume. The Lightmass Portal directs where openings are (for windows, doorways) to direct them through the opening for better results.
