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"

Why does my light bleed

There is always light leaking in my scene from the top of the walls even if i don't have any light source

I tried to solve this problem by remapping UV's but didn't work.

  • I am new at UE4 so i can't figure this out.

Hello Kediko,

I have a bit more information I would like from you in order to better understand this issue.

  1. It looks like the walls and ceiling are not the same object. Creating a structure using only one piece of geometry will help resolve this in the future.

  2. From your screenshot you have a Min Lightmap Resolution of 64. Change this to 256 or 512 for your ceiling and walls.

Let me know if these troubleshoots help. I think #2 would bet better in this situation.

Logan

Hello Logan,

Thank you for your helps. After your answer I recreated my walls and the ceiling as one object.

The problem seems resolved now.

  • P.S. Sorry for delayed answer.
