I am sorry for the reply delay-I decided to leave that issue alone and try to keep developping on UE4.2, where the problem doesn’t occur. But well, now I figured out that I should keep up with the newer versions of engine.
I cannot record a video, though-my hardware is too weak, UE4 alone makes it sweat. But I will write it down step by step:
- Create a new blueprint, lets call it “Child”
- Set its root component to be a static mesh component
- Enable “Simulate physics” for the static mesh component
- Obviously-set some static mesh for it, “Shape_Cube” will do
- Create a new blueprint, “Parent”
- Add a scene component to it
- Add a “Child Actor” component to it
- Set the Child actor component’s class to the “Child” blueprint
- Spawn a couple of Parents around the world
- Hit “Play” button
This will definitely lead to occurence of what i mentioned before. I tested it on a brand-new “Basic Code” project in UE4.4.
Important: The problem doesn’t seem to appear, when the Child has a Scene Component as root, and Static Mesh Component attached to it.
