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"

Landscape dominant layer lost when changing collision mip level


It seems that dominant layer info in landscape collision components is lost when changing the collision mip level. For a repro open the attached project and run the Landscape map. You should see the sphere falling through the hole in the middle. If you stop the simulation, change the collision mip level to 1 and re-run you will see the sphere landing on the landscape. Could you have a look at it?

Hi luis.valverde,

Hi Luis, Thanks for your report. This was fixed for Unreal Engine 4.8, and the source code change can be found here:


This fix should also be in any of the 4.8 preview versions if you want to try.

Thanks Jack
