WW4 Extended is an unofficial expansion for the WW4 modpack, the OFP & CWA mod that focus on performance. It covers modern, Cold War era and Arctic warfare, adding numerous infantry units and vehicles for all sides, and provides several visual and sound effects (tracers, bullet cracks), support options and many other features.
What building is that? I don't remember it...
(BTW: being unable to remember objects from mod I've had privilege to work on. That's an evidence of EXT gargantuan size!)
It's a port form an Arma 1 one. Although it was actually ported also to A2, and that's from where I got it from (via the public BI models).
You can find it in: WW4 EXT/ Objects(W)/ Ruined Building (2 floors)
Original model was AFbarabizna.p3d.
As with the rest of the ports, it's a mix of several LODs. It has the general shape of the second LOD from the original, but details such as the stairs are from the first LOD. Just to keep it as low poly as possible without losing too much detail.
Fortunately this object had both roadways and paths (for AI navigation and positioning) so, unlike may other ports, I didn't had to create new ones here.
This building is also an enterable version of the old OFP one you can find in some spots of Kolgujev.
Yeah, I've found it and indeed it seemed familiar ;)
