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 problem when a mesh wakes up

Hi,

I noticed a problem when I wake up a static mesh. For a short time after setting "Set simulating physics TRUE", the mesh can penetrate any other mesh but if I wait a little then collisions are working normally.

Here is what I do :

  • Put a mesh inside a open container and deactivating its physics simulation

  • Grab the mesh with a physics handle and reactivating its physics

  • If I don't move the mesh during a short time then it collides normally with the container

  • But if I move it right after grabbing it, it will go through the container

I tried many things like CCD and substepping but nothing seems to affect this behavior. It's like there is a short period after a wake up when collisions are ignored.

Is it a bug or can I do something to prevent this?

Hi VRMD,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?

  • Does this occur with all physics objects, or is it limited to a particular asset (for instance, a skeletal mesh vs. a static mesh, etc.)?

  • What collision settings do you have on your physics object?
