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"

What is the purpose of VehicleWheel Shape->CollisionMesh?

I don't understand the purpose of the "Shape" section of the VehicleWheel blueprints. It doesn't seem to have any effect.

For example I can choose "cube" and the vehicle behaves just as if it were cylinder. A cube doesn't show up when i visualize collision either, the tires show a sphere (which matches what's defined in the phat physics body).

"The wheel Physics Bodies are never actually used for collision. Currently, the wheels use a ray casting for interacting with the world." from there: https://docs.unrealengine.com/en-US/Engine/Physics/Vehicles/VehcileContentCreation
