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"

I have already checked the plugin.And i found that the simulate physics checkbox is grey that i can not enable it.alt text

couple things to check. the "num segments" needs to be greater than 1, and the Gravity scale needs to be greater than 0.

For sure,man.I have checked those two parameters.And it works on game model right now,but still can not work on editor.

there is a little drop down menu in the top left of the editor. Make sure "realtime" is checked. ctrl+r is the shortcut.

I think you need to change length.

Can you provide screenshot/s of cable and cable forces?
