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"

Vehicle wheels don't collide with ground

I’m trying to create a vehicle but the wheels won’t collide with the ground.

My root bones and all my wheel bones have X facing forward, Z up. Root bone is at 0,0,0. alt text

Using pxvis collision console command, I can see that the wheels appear correct and the center of masses are in the correct place. alt text

In my physics asset, when I simulate with my wheels set to Kinematic, nothing happens. When they are set to default, they collide with the ground (but roll incorrectly because none of the axis are locked). alt text

When I run the game my vehicle body collides with the ground but the wheels go right through. Unreal has image upload limit but I took video of that here: https://i.imgur.com/tYnyyUm.mp4

Solved it. You can't have three wheels native vehicleMovement class. Adding a forth wheel and attaching it to the same "rear wheel" bone makes it work as expected.
