Well, I feel those 3rd party implementations are not that good. I mean they don’t really clear it but rather smear it.
Having said that, I am basing my expectations from observing car windshield wipers, I have got no idea how they work on the actual planes. But common sense dictates that they should work at least similar to the car windshield wipers.
So a native proper method of windshield wiper effect would be nice to have in 2024.
Yes, I think it could be better. But I think those who have managed to get water to physically interact with the wipers are at least on the right track, and have done everything possible in the face of the current limitations of the core engine.
Well. I opened a new discussion topic with the hopes of discussing it with the community ( in the discussion forum ) and potentially getting developers’ input on the development status. Instead, my topic was merged into a lengthy discussion that would just get lost.
After the last development stream, it became apparent that the senior development team might be missing out on the general sentiment of what active “pain points” are in our user experience and unaware of particular topics related to the wishlist/bug items. Maybe the reason is that we have the same old extended topics that just get lost in the haystack, and since they are the same old topics, why look at them? If mods are going to take every new post and catalogue them into old topics, where is the point of having a discussion forum on it?
Yes precisely.
Well, we are two months away from the launch of FS 2024 and we still have no news about whether they will work in the new simulator, sigh…
If you watch the live from CptCanada earlier today, he claims it does work, but there’s still no video anywhere of that being truly the case. He says, “the wipers do work, I believe so”… which makes me wonder if he just thinks they work vs. he actually saw them.
Straight from El Jefe’s mouth. It works!
I know I’m sad, but this will probably be the very first thing I test. 
Stop moaning, they are fully immersed in making animals photogenic 
Glad to see that. It’s too bad they didn’t have something to show us, but I guess in time. Maybe during an upcoming demonstration, someone will think to check it out. Of course, ol’ Randazzo will probably tell us that it’s a knee knocker of a problem and it’ll cause more delays (I’m kidding, but seriously lol)
As working wipers are a higher priority topic many asked for I think they will talk about it/show it during a developer stream. Either the next one on the 25th or the one after.
They work on the Canadair CL-415. 
They work on the BBS Short’s as well. They give the illusion of moving water away with an area of the windshield that does not show rain.
They actually work on many aircraft, especially on the Fenix and on inis Airbusses.
The only thing is that the process to enable that isn’t standardized and documented in the SDK - also none of the other default aircraft currently have got working wipers which will certainly change
Technically Asobo may use a new shader with a region defined using vertex colors on that an animated wiper wipes “water” away. In theory, if they add another vertex color to the wipers blade. This way that effect could be pretty detailed - the shader could detect the wipers movement within some margin (~1cm or something) and create smear on one side of the wipers path and water building up on the other side. The only question is how much performance that would eat 
Honestly, I’d be happy with the effect from Train Simulator Classic at this point, but I know the Asobo engine should be capable of a more realistic effect. According to the dev livestream, wipers are working in FS2024 yay!!! 
What about water landings splash? It is such imersion breaker not to have even few droplets on windscreen… 
Fixed in MSFS 2024? I hope so.
