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"

UE4 Lighting Errors

I'm currently creating a Sci-Fi game. I am creating my levels out of modular assets I have created. All of these assets have depth and snap together seamlessly.

When I build the lighting I would like the gaps to seem seamless. The images above show the result I am getting. They are all using the same colours and roughness on the materials but seem to all have differents shades when I compile. alt text

Another problem I am having is this. I have checked everywhere and there doesn't seem to be any holes in the wall but I am still getting this strip of light along the floor when I compile. Any ideas of how I could possibly fix these problems? Thanks

are your vertices in EXACTLY the same places? what do the model normals look like?

For the floor light strip you could pop a blocker behind it. Check your vertices are in absolute alignment like Nuclear suggested. Could you post a shot from further back? It's hard to see the roof geo or what might be causing your issues from your shots. Also I'm not sure which strip of light in your 2nd image you're referring to, could you ring it for clarification?

Thanks for the suggestions, however, I managed to fix it by combining all the meshes into one.
