How do i start the rigid body dynamic in the keyframe i want? I’ve been trying to animate a blowing skull, but, when i try to add the active rigid body dynamic, it stars from keyframe 1, when what i want is to start it in the keyframe 267.
Go to frame 266.  Select your rigid body.  In properties/rigid body/physics/settings, check Animated and keyframe it.  Go to frame 267.  Uncheck Animated and keyframe it.
