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"

Doesn't Instanced Static Mesh have friction?


Please watch movie first.
I want to carry white boxes on the red and blue boxes.
The red box is an Instanced Static Mesh Component.
The blue box is a Static Mesh Component.(Reference)
White boxes are Static Mesh Actors. These are simulated physics.
This is a minimized sample. Finally I want to use only Instanced Static Mesh Component because I want to use so many carriers.

Red and blue boxes are moved their locations at Tick Event. alt text

But it doesn't work on UE4.19 and newer. It works on UE4.18 and older.

Do I need to set the additional settings on UE4.19 and newer? Which is the regular behavior? Which is the bug?


Product Version: UE 4.21

I had a workaround.

I use both of ISM and SM simultaneously. ISM's colision is set to OFF. Only for showing. SM's visiblity is set to OFF. Only for collision.
