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"

Sky/Directional Lights messing with lightmap

Hey guys,

At first, while working on it, I used several point lights through map to lighten it, just like this: alt text

Then, when I removed them as I was done with models, the ceilings began to have light issues (SAME texture as columns and walls), appeared some occlusion issues too on some rocks (both 2nd pic), and the landscape went buggy with light too (3rd pic) alt text alt text

Anyone know what this issues are caused by? Here are skylight and directional light specs: Sky alt text Directional alt text

I'm having lots of problems with directional lights from 4.21 on.

Seems the system is broken now, also broken in 4.22. Same scene in 4.19 works completely different using

I just filed a bug report.

Did you get any official answer?

I found an answer, you should use this plugin as Unreal team seems to ignore us. Some customers made a great work while the staff didn't:
