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"

Align hovercraft to ground normal

I'm trying to align an hovercraft to the ground direction to make it follow the ground surface. I substract the up vector by the impact normal under the hovercraft and add the result to a torque.

It's close from working but when the hovercraft change orientation the torque is turning the hovercraft in the wrong direction.

I can't figure out how to make the torque working the correct direction.

Any suggestions ?

Searched for hours, post the question then find the answer in 15 minutes ;-) from the idea behind : https://answers.unrealengine.com/questions/4925/question-possible-to-get-landscape-polygon-tangent.html

The solution is to use cross product instead of vector substraction.
