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"

Getting Invalid Simulate Options Error When Setting Simulate Physics On

I'm trying to set simulate physics on for a skeletal mesh rifle I have. Whenever I do so, I get an error that says "Invalid simulate options...set to simulate physics but collision enabled is incompatible." (warnings.png). I've attached two collision settings I've tried (collision.png and collision2.png) When I put custom world static collision and take off the simulate physics, I get no error. When I set collision as a pawn (and query and physics enabled) on the skeletal mesh but no physics, I still get the error. When I set collision as a pawn (and query and physics enabled) on the skeletal mesh and set simulate physics, I get the error and the weapon doesn't remain attached at the socket, but just hovers in the air. BUT when I attach the gun to a socket, I am spawning a new weapon and disabling its physics and collision completely.

The strange thing is that if I start off with no collision or physics enabled on the skeletal mesh, and then in the game drop the gun (by spawning a new one and enabling physics and collision), there is no error either. (dropgun.png).

Can someone please tell me why this is happening and how to fix it?alt text
