Invisible fragments

[pavlo-kravchenko]

Hello
I ran into a problem and maybe you could help me solve it.
If I create an object from a prefab, instead of being destroyed, it just disappears. (In fact, it is destroyed and just falls but to invisible, regardless of the settings.)
The same thing if I just move it from the prefab to the scene.
However, everything works fine if I
1 Move from the prefab to the scene
2 Click generate fragments

Work
