Rope breaking was added rather recently, a few months back, so the 4.13 build will, unfortunately, not have it. If possible, I’d recommend upgrading to 4.16 at least. As for having it break/cut by projectiles: certainly! The only thing that you’ll have to figure out is when and which particle to cut at. The collision events are not yet implemented, so the tricky part for now is figuring out which particle/segment to cut at and when.
Ropes being static means that the plugin failed to find and load the needed DLLs. What folder is the plugin in? Is your project Blueprint-only or with C++? Is the plugin from the Marketplace or from my GitHub repo? If my repo, what branch? Is the Engine from the Launcher or from GitHub?
The 4.13 loading was a bit picky if I recall correctly, but shouldn’t be too difficult to figure out.
The example project crash may be related to the above, but I’d need to see the full log to confirm.
