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"

[Closed] Simulation problem in PHAT if bone is marked as kinematic


I didn't remember such issue in UE3. When one of a bone of ragdoll is marked as kinematic simulation is completely broken. I'm able to reproduce this issue in 4.4.3 ShooterGame example:

  1. Download 4.4.3 engine version

  2. Download ShooterGame for 4.4

  3. Open PhysicsAsset'/Game/Characters/HeroTPP/HeroTPP_Physics.HeroTPP_Physics' in the PHAT editor

  4. Mark for example b_Spine1 as kinematic

  5. Start simulation and observe the issue

Only 'hips' bone marked as kinematic works as expected:)

Dunno, may it be, but We will wait for EPIC response.

Hi, I checked this issue in 4.6 and it works better than in 4.4.3 but problem still persist for certain bones:

  • b_Hips, ok

  • b_Spine,ok

  • b_Spine1, almost ok, but for some reason the ragdoll is dragged by b_Spine1 body under the ground

  • b_head, almost the same case as b_Spine1 but the ragdoll is falling forward

  • b_LeftUpLeg, woohoo the ragdoll is rotating around hips

  • b_RightFoor, broken the ragdoll is dragged under the floor

When body is marked as kinematic, it should stay where it was before simulation. Why am i even reporting this? I think if it reveals here it may reveal somewhere else.
