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"

Lights blocked off in a certain direction

Hey guys,

I'm very new to UE, and I'm finding some problems with adding some lighting as a part of character component.

What I'm seeing is that when I add a light attached to to the root component, the light looks like it's being blocked by something in a certain direction.

I don't have any other geometry in the scene other than the floor and the walls (it's the 3rd person code template), so I'm not sure what is happening.

Does anyone have any suggestions of what could be wrong?

Hey xiaozhes,

I haven't been able to reproduce the issue you are experiencing. Could you post some images of the light components' setup in your character Blueprint? It may also have something to do with the floor material you are using, so if you wouldn't mind attaching that .uasset file I can look into that. Thanks!

Hey xiaozhes,

It looks like your lights are working fine. What's causing this lighting issue is the material on your floor. The texture you have plugged in as your Normal is not actually a normal map, and removing it seems to fix the problem.

You might need to look into creating a normal map using a different method than whatever you used the first time. Here's a tutorial I found that mentions a couple different programs that can help you create a normal map from your texture:


Hope that helps!
