Using doodad skins for units\destructibles

[Gluttony]

Hello!
I would like to use doodad skins for units\destructibles, but in editor they are shown with black-green checker box cube instead. How to fix it?
As an alternative, if I can spawn doodads with triggers, that would work too

Skins? Most models work fine for me:

^ That's a copy and pasted Barrel (destructible) using a Building model (doodad).

The cube problem might happen if you set your destructible to have multiple variations like trees or crates, set it to 1 and it should work fine

Specifically, I'm trying to have a destructible that uses fissure model
If I set it for any variation (1 or 2) it always gets cubed, if I set it for base it occasionally works
