Mh, i flew the PMDG 737-600 yesterday and the wipers cleared the windsheeld, the raindrops were gone...although the area is perhaps a little bit too small and more to the bottom-center of the windsheeld. Will check this again, but i am pretty sure, it was not just imagination :)

My bad... (as the kids say!) I flew the 738 in rain only sometime ago and could swear blind there was no clearing of raindrops. I just took a look earlier, and yes, you're right, but to be fair, the animation is not as convincing as it has been in previous sims, ie P3d. But it's certainly a step up from not having it at all.

I feel like cloud bases are fairly uniform.

Ryan is mostly correct with his descriptions in his post. In addition to the virga that he points out, storms, especially heavy storms, may at times also be accompanied by lower cumulus fractus clouds, often referred to as scud, which do not have uniform bases.

It is also common for layers of cumulus clouds to be accompanied by higher levels of clouds, such as altocumulus and altostratus, and even cirrus, which are yet higher. Those layers have their own base levels. And those have base levels that unto themselves are also quite uniform.

I have not yet seen a weather engine with textures that represent all cloud types, and especially not render multiple cloud levels together in a proper sense. In my experience Active Sky 16 (2016) for FSX and X-plane did those best. MSFS 20 & 24 appear to present challenges to multi-level rendering, especially cirrus cloud types.

Haha, just imagine it as a cost saving company advise not to change the rubber of the wipers before they are nothing more than an idea...so the animation is as real as life can get ;-)
