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"

Collision Sphere attached to SkeletalMesh with 'Collision Enabled' collides despite of being set to 'No Physics Collision'

Hi, I will explain the bug while listing the reproduction steps.

  1. Create a new Actor Blueprint.

  2. Add a SkeletalMeshComponent

  3. Set Physics->Simulate Physics to true

  4. Set Collision->Collision Presets to 'BlockAll'

  5. Add a SphereCollisionComponent and attach it to the SkeletalMesh

  6. Make sure it is set to 'No Physics Collision' (should be set by default)

  7. Make it big enough to see that it collides with terrain

  8. Place the newly created actor on level and simulate the game

  9. Notice that the new actor collides on the sphere despite it being set to 'No Physics Collision'

I'm pretty sure this worked fine pre 4.8. There is a hack to fix this and it looks as following: alt text After doing this 'trick' everything works fine again.

PS. FYI this works fine with static meshes.


Product Version: UE 4.8
