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"

Physics animation glitch on spawned actor

alt text

I made a character in which I activate physics animation. If I put a character on a map in the editor, everything works fine. But if I spawn a character in the game, the physics animation does not work correctly. Maybe someone knows this bug and how to deal with it? alt text

1_I spawn character with physical animation turned off, after delay physical animation turned on = physical animation work incorrect. 2_I spawn character with physical animation turned on = physical animation work incorrect. 3_Place character in editor with physical animation turned off, after delay physical animation turned on = physical animation work good. 4_Place character in editor with physical animation turned on = physical animation work good... ...Looks like some time physical animation spheres ignore constrain limits or physical animation data setting.

1_I spawn character with physical animation turned off, after delay physical animation turned on = physical animation work incorrect..

2_I spawn character with physical animation turned on = physical animation work incorrect...

3_Place character in editor with physical animation turned off, after delay physical animation turned on = physical animation work good...

4_Place character in editor with physical animation turned on = physical animation work good...

...Looks like some time physical animation ignore constrain limits or have wrong physical animation profile or ignore physical animation data settings... AI character can switch skeletal mesh and animation blueprint, i feel what root of trouble some where here but i have not enough of fundamental unreal engine knowledge and need help.

I place the comment but it gone. I repeat short version of comment. 1_I spawn character with physical animation turned off, after delay physical animation turned on = physical animation work incorrect. 2_I spawn character with physical animation turned on = physical animation work incorrect. 3_Place character in editor with physical animation turned off, after delay physical animation turned on = physical animation work good. 4_Place character in editor with physical animation turned on = physical animation work good... ...Looks like some time physical animation spheres ignore constrain limits or physical animation data setting.

Try making a new blueprint for testing and setup physical animation on that one and see if you can get the same problem to happen when spawning in this new actor. If so, that way we can rule out any problems in the existing character blueprint. Additionally, you can try changing the body sizes/transforms and make the constraints set to free in the physics asset to see if it behaves any differently.

Physical animation is quite fiddly. I have not seen this particular one before. But as a suggestion perhaps try spawning the character without the physical animation turned on, then later, once it is actually spawned, turn on the physical animation.
