For some reason I cannot place sirens on emergency vehicles. The place for the siren does get marked but with the red colour instead of green, so i dont know whats going on

This is a packard issue for UNU and should be reported in their server.

Either that or Trin. One of the two is not working within conventions set between one of the two. They need to talk and figure out the standards. Will leave this up until such a time for visibility.

It's an UNU thing, that's an UNU gyrophare and an UNU lightbar, I'll look into it and update the UNU Parts Pack.

I don't know if that should be taken as an insult or a compliment that I'm confusing UNU vehicles with Trin. ;)

They sorta did, but Trin gyrophares only go in specific spots and not in siren/lightbar spots IIRC, and so likewise don't take UNU siren lights as gyrophares. So yes mostly completely except for this, and vehicle-specific parts. (which I don't really expect, nor want, to be interusable... a Trin Rodeo softtop probably wouldn't fit on a Contractor)

tl;dr yes but seagull plz hry (:

In fairness it would be nice if Trin emergency vehicles could directly take gyrophares though, I think that was planned even. Don't quote me on that though...

I thought that both Trin and UNU had cross-compatible parts? Or did that only extend to the wheels/seats/engines? Cause I do recall Seagull made his lights parts whereas I think UNU's emergency systems were built-in to specific model variants, so perhaps Seagull didn't establish a convention on the lights when he was making them?

Gotcha. @DrprofLuigi whenever this gets patched can you let me know so I can close this ticket?

@DonBruce64 This is fixed in UNU V4.4.2
