С++ and BP inheritance

There are 2 BP classes. They have same comopnents: DefaultSceneRoot, StaticMesh and InterpToMovement, same variables, same construction Script. The only difference (i think so) is their parent class. One is based on Actor (add new BP class->Actor), the second is based on my C++ class which is based on AActor, I didn’t change it (c++ class) after creation. The first is good, but the second ignores collision during movement and move through other objects. Is c++ bad or i don’t see something? Pls Help :slight_smile:
