So are you saying that you are experiencing this when someone appears in your session
- never mind what they're flying on their own machine -- as something other than a Carenado aircraft? All the reports you have listed in this thread have involved a Carenado aircraft being injected as multiplayer/AI models.
As spokes2112 says -- it is not about what YOU are flying, or indeed even what the OTHER person is flying. It's what is PORTRAYED on your side by the model matching.
As I said, vPilot users had the same problem --> remove Carenado models from model matching, no problem any more, which seems rather co-incidental doesn't it? The fact that it is not all Carenado aircraft I imagine is because the older models probably don't have the same anti-piracy measures included.
As far as I can see from what has been reported:
1) If I the Carenado Cheyenne III on my own - no problem.
2) I fly the Carenado 310. Somone else joins flying on THEIR machine, I don't know the A2A PA28, which is subsequently aliased by JoinFS on MY MACHINE to display one of the affected Carenado aircraft. In this situation, the Carenado aircraft that has just loaded on MY MACHINE activates the anti-piracy protection and cuts my engine.
This is not the fault of the A2A PA28 that joined, it is the Carenado aircraft that was displayed on my machine
3) Imagine the situation is reversed and I am flying the A2A PA28. Someone else joins in the Carenado, but I don't own a Carenado aircraft so it is model matched to a default C172. No problem.
4) Alternatively, however, I am flying the A2A PA28 and someone else joins in the Carenado 310. I happen to have this in my hangar and set up in my model matching, so the other party appears as such. Guess what? As soon as the 310 loads on MY PC, the anti-piracy protection kicks in and cuts my engine.
5) Finally, let's say I'm flying around in the default C172. Someone else joins in the default C172, but for some reason I have that aliased in my model matching to the Carenado 310R. What happens when the 310R loads on my machine? Yep -- anti-piracy kicks in and cuts my engine.
You solved the problem for yourself some posts earlier:
I ran into a vicious loop today... loaded up in the Carenado Cheyenne II...a friend joined, he was in the Milviz 310 and I model matched him into the Carenado 310R.
The 310R was triggering engine cut out, and was bouncing up and down, every time reloading and i couldn't keep my engines on for more than ~20 seconds... matched him to a UTlive AI and all was well...
As mentioned above, the easy fix for this is to just exclude all Carenado models from model matching. That doesn't mean that nobody can ever fly a Carenado aircraft again, it just means that you can only have ONE (i.e. the one you are flying, if that is the case) displayed in YOUR SIMULATOR at any one time. You could have 300 people all flying Carenado aircraft if you want, PROVIDED that they all load as something else in everyone else's model matching.
