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"

Lighting resolution not taking effect with brushes?

I am getting non-realistic shadows after having build lightning with the preview configuration:

alt text

As can be seen in the picture, the lightmap resolution is set to 128; if I set it any higher and click build, it is reset to 0 and no light can be seen on the floor. What is that about?

Hi Univise,

With BSP brushes you can't use normal resolutions like you would with Static Meshes. You have to use lower values to get higher quality.

Have a look at the Lighting Troubleshooting Guide I put together here: https://wiki.unrealengine.com/LightingTroubleshootingGuide#Lightmap_Resolution_.2F_Shadow_Quality

I hope this helps.

Tim
