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"

Splotches on Lights Reflections

Hi, I have an issue related to UE-19818 and UE-42488:

alt text

I am using ForwardRendering now but I am having this problem since 4.10 a year ago. The "fix" was since then to make the lights non-visible so I don´t see them on the reflections after baking the lightmaps. On the scene I have static spotlights with the default minRougness=0.08 and sourceRadius=~3. Depending on this values the annoying splotches appear or disappear on the reflections:

minRoughness=0 to 0.999 ---> SPLOTCHES

minRoughness=1 ---> NO SPLOTCHES

sourceRadius<~3 ---> NO SPLOTCHES

sourceRadius>~3 ---> SPLOTCHES

As it says UE-42488 even if I change the minRougness there are not visible changes on the scene so this parameter is not working since I activated ForwardRendering. But is interesting that when this parameter is on its maximum value (1) the splotches dissapear. What I found about the sourceRadius is that when the value is around 2 or 3 this splotches appear and they slowly get blurred when the value is more than 10 or 15.

Product Version: UE 4.15

Same issue on my side running 4.15. Source radius of 3 to 10 approximately, causes these ugly splotches.
