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"

Custom Collision mesh import

While trying to find a workaround for this: https://answers.unrealengine.com/questions/198275/mesh-collision-not-working-with-physics.html I found this bug where the imported collision mesh is very simplified in UE4, I also tried it splitting it in 2 collision meshes in 3Ds max but in UE4 it was then the same simple shape just split in 2:

As suggested in answer, you need to split up your collider to convex elements and use naming convention for proper import. Refer to FBX Import Pipeline documentation .

Hey Davision -

Collision Meshes cannot have any Concave elements, the engine will automatically fill in the concave portions if you try to import it into the engine. If however, you divide your mesh into multiple sections you can achieve the collision you are looking for. I did a quick example for you here I have a 4 pointed star mesh that I want to have exact collision and in order to do that I need to make 3 separate meshes with no concave elements to get the shape:
