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"

Translucent material issues on Mac


I got some issues with my translucent materials on MacOs devices, this issues appears on packaged builds and sometimes in Play In Editor (But usually, in PIE works fine, except the atmospheric fog that is always black without opacity).

The translucent area appears to be black or pink, depend on the level that I'm on, also, it happens the same thing with the Atmospheric fog of Unreal

Some examples (left the image from windows, right the image from Mac)

Lobby Level:

InGame Level 1:

InGame Level 2 (with Atmospheric fog):

alt text (On that level, if I use the shield that was pink on the last screenshot, it is completely black)

I tried changing the r.TranslucencyLightingVolumeDim (that solved some similar issues on PS4 builds) but without any luck

That happens with all my translucent materials and particles, any thoughts? Thx in advance
