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"

"Self-Shadowing" on Tessellated ground broken from 4.18 to 4.21?

While going from 4.18 to 4.21 the self-shadowing on my snowy deformed ground stopped working for point lights. 4.18: alt text 4.21: alt text 4.21: Directional and spotlight works. point (and rect) doesn't alt text Is there a simple setting I've forgot somewhere? Cast shadows is on for all lights. They are set to movable. Is point lights not the best type of lights to use?

I've searched for clues and the closest I've found is this, but there's no mention of point lights in there even: https://answers.unrealengine.com/questions/392144/terrain-tesselation-and-dynamic-shadows.html

It's not quite the same material - I got the snow trails blueprints from the marketplace to replace my own solution made in 4.18, but even so, it shouldn't matter since the spotlights seem to work still.

Any other recommendations for settings in this use-case would also be appreciated!

Product Version: UE 4.21

I am also having this issue! Plain white material with displacement doesn't receive point light shadows, but the spotlights work just fine. At first I thought it was because I was using subsurf, as that is a listed limitation, but it seems to be broken for default lit materials as well.
