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"

Weird Shadows

I'm new to UE4 and I'm making simple achitectural/interior design visualisations and walkthroughs. I imported this tent structure to UE4, textured it, and baked the lighting, but underneath the tent I get these weird light squares where there should be shadow as if the light is passing through the tent at specific points.

The tent is a single surface with a double sided material and double sided lighting. The interior of the tent also seems to be too dark, although that may just be due to the fact that there are no lights inside.

I've been through the light troubleshooting guide but none of the issues seem to be the same.

I managed to improve the lighting by giving the surfaces thickness in my 3D editing program instead of using double sided materials in UE4, and by increasing the light map resolution.

If anyone has any better methods for improving this please feel free to add
