Yes, it was a mod
No wings breaking explosions mod .
However, only WOFF3 compatible at this moment. In case of interest I can create/release WOFF UE version (which I use personally now).
I'd certainly be interested in the UE version Triple J
OK, Adger, I will try to add this mod definitely to my Multimod, avoiding possible conflicts with other JSGME mods that can modify/alter the Simulation.xml file.
