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"

Why is Simulate Physics grayed out for the Root component in my Blueprint?

I need a blueprint to react to physics, so falling and having forces applied to it. I have a static mesh as the root of my blueprint, but in the physics panel the simulate physics toggle is grayed out and i cannot edit it. How do I fix this problem?

Hey mdagreda,

The root of a Blueprint has some limitations on what you can modify. You can create a Scene Component in your Blueprint, and make that the root. Then you'll be able to modify the settings of it's children.

Hope that helps!
