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"

There are two types of lighting in UE4.

  • Static (Lightmass)

  • Dynamic

Static lighting is need to be build and not changes in gameplay (well, except lightmap reloading, but it's require completely different setup).

Dynamic lighting is not "baked" into geometry and can be moved. It has tho limitation on amount of light channels and it's heavier on GPU load.

There's also Stationary option, it's the same as Static but brightness and color could be altered (it still won't affect GI).

So for moving light it should be "movable". It can't be "baked"(build).

To rid of Lighting need to be rebuild warning You have to Build the Lighting: https://docs.unrealengine.com/latest/INT/Engine/QuickStart/6/

You could find all the info on docs, here: https://docs.unrealengine.com/latest/INT/Engine/Rendering/LightingAndShadows/index.html
