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"

SkeletalMesh SetCenterOfMass() ?


Ok this one has been bugging me for way to long, how the hell does the SetCenterOfMass() function works on a skeletal Mesh? On the attached screenshot, I'm just setting the center of mass at (0.0, 1.0, 0.0) and it's offset on the Z axis by 65cm, seriously...

Thx, aalt textny help greatly appreciated!

Ok, so I've got a final answer to my question.

Why are the axis wrong? Because the Axis used are the one coming from the orientation of the physics body set in the Physics material assigned to my skeletal mesh. In my case I had selected "do not orient to bone" when generating the body and I ended up with Y down and Z right.

Why are the unit wrongs? Because Physx uses m and cm like unreal. I don't get that as most forces and velocity are always returned in cm/s.

Finally if a function sets a center of mass Offset, I think it should be called "SetCenterOfMassOffset"...
