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"

Hello Stunt Thumper,

To change the mass within your physics assets you need to change the the 'Mass Scale' of the object. Simply go into your physics asset and within the 'Details' panel you can change the 'Mass Scale' of the object. Here is an image to help you locate what I am talking about as well as some documentation on Physics Assets and their modifiers.

You can also create a new 'Physical Material' and apply this to your 'Physics Asset,' which allow for even greater control over the way your object is used with physics in the engine. After creating this 'Physical Material' hover over each setting to understand a bit more about what and how it affects your object.

I hope this helped!
