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"

BSP Surface's lightmap resolution settings work oppositely?

Setting the light map resolution (under surface properties, lighting) to a lower number increases the resolution, and setting it to a high number decreases the light map resolution??? This can be seen by changing the view mode to light map density, and just by seeing the shadow qualities (better on surfaces with lower "lightmap resolution" number). Is this intended?

Hi Hand_of_Cthulhu,

Lightmap resolution is meant to be set lower for better shadowing. This is mentioned, albeit briefly, in the docs here: https://docs.unrealengine.com/latest/INT/Engine/Actors/Brushes/#brushproperties

Lightmap Resolution - Essentially allows for adjustment of the shadows across this surface. The lower the number, the tighter the shadows.

I've also mentioned this in my Lighting Tips and Troubleshooting guide here: https://wiki.unrealengine.com/LightingTroubleshootingGuide#Lightmap_Resolution_.2F_Shadow_Quality
