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"

Box Collision non-uniform scale issue

Hi, while scaling object using box collision ,collision scales wrong.See picture below

alt text

Cylinder in the left is the imported mesh using UBX (box) collision without any scales,these two in the middle are the same cylinders with scale values of (3,1,1) and (1,3,1), rightest one is the same cylinder but this time using the same box as UCX (convex) collision and it works correct. What is the problem with box collision.

Also:the blue wireframe is collision?

Product Version: UE 4.14

Check the pivot of the collision volume vs the pivot of the visible geometry. It seems that scale is applied to each component in its local space rather than the object as a whole.

Thanks for reply. I tried the same thing with an asset where pivots are perfectly the same (just created a cylinder and a cube in center of scene) and nothing changed.Looks like there is an issue with UE4 import.But I could avoid that problem by just creating box-collisions in UE4 Editor (not in another 3d software ) and everything worked correct. .Of course that is not the right solution of this problem.
