the black is comming from the cockpit and other parts as a reflection. It wouldn’t be there without TAA if it shouldn’t be there. FS20 uses a good amount of real time SSR, which means that most things, including the rain fx, will be taken into reflections (unless out of the screen limits). There are also complex transparent bodies effects, like the ones in the air entries and Im quite sure the rain strips too, so if rain strips look like that without TAA, I think thats the accurate version (except with jaggies of course). TAA is very picky and can make odd effects with certain things, I think thats one of them, in fact, the effect is barely visible so I dont think thats intended.
