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 broken on Foliage Mesh painted on Terrain


We have a bunch of foliage in our Map, and some is painted on static mesh and some on a terrain. The foliage painted on the terrain glows with bright primary colours after lighting is built. (the terrain is the water in the screenshots)

Both the foliage on the terrain and on the static mesh are tagged not to cast any static shadows.

alt text Lit

alt text Lighting Only

alt text Unlit

Anyone have any idea what could cause this? it makes working in the editor next to impossible with all the bright neon bloom!

Take a look at this thread: https://answers.unrealengine.com/questions/48362/strange-foliage-glow-issue.html :)

"Does the artifact go away when you set the 'r.Cache.LightingCacheDimension' console variable to 128? There's a bug with many (>1728) movable components right now that will cause this. Instanced foliage currently does not support lightmaps correctly which are used when the components have static mobility, so both routes are a bit broken. "
