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"

Skylight & Reflections

In this Documentation page, they say that you should avoid a shadow casting skybox:

Common errors preventing Lightmass indirect lighting from working after a build include a shadow casting skybox, lack of a LightmassImportanceVolume, missing or incorrectly setup lightmap UVs, or Force No Precomputed Lighting being set in the World Properties.

What does this mean? Is it not possible to have a sky light with shadows in a scene using reflections?

Hi Robert42 -

No, the Shadow Casting Skybox is referring to the object on which your sky material is placed, in default projects it is the BP_SkySphere. You can absolutely have Sky Lights cast shadows if needed or wanted.

Thank You
