Weather engine(s)…errm, which one? / REXE+OD released!!

Recently, I had a chance of trying out the latest presentation to our hobby, Opus Software weather engine.

Now, I will also state that I’m a long time ActiveSky user, and when Opus came out I was as always inclined to try it out.

While ActiveSky has been putting mostly quite nice displays, and finally I was flying calmly with realistic wind changes, no sudden changes, my fuel planning and prediction was correct and that was one real neat thing.

When Opus came out, many were raving about how it correctly depicts the weather from horizon to horizon. That is correct – it really does. Why? Because it is station-based METAR-based weather program. Something we had from ActiveSky 7 years ago. We still can have it in the basic depiction mode. But there is one big downside in this mode – there is no possibility to smooth out wind changes, and definitely no chance to have correct fuel prediction for airliners. I tried this myself, I planned the flight normally, entered the data from AS, then flew with Opus. Terrible. My fuel was way off, wind shifts all the way, getting stalls in the NGX etc. Of course, if I turn on FSUIPC smoothing, things were somewhat better, but if the wind shift was severe, even that didn’t help enough. Finally I had to give up with the NGX.

Then I flew with Cessna around, and noticed how it was actually quite nice with Opus.

Conclusion is quite simple: Opus is *currently* only for low and slow flying, giving a nice cloud representation, current METAR, and that’s it. Go higher and you come into problems.

The team behind the Opus is, as they say, at hard work to implement those wind shifts. It’s always nice to see competition in our hobby, but there is one thing rubbing against my brain: what can they think of that HiFiSim can’t? Can they?

On the other hand, the amount of dedication from Opus development team must be noted, and said that their support is very active on the forums, trying to help users out.

HiFiSim is currently also bringing SP2 out for the ASE and should by their words be really spectacular.

Also, additionally, currently released new weather engine, REXE+ is out and has yet to be tested. Also implementing full wind and temperature management and apparently correct flightplanning. I am yet to start playing and checking it, but I hope it’s good as they say it is!

So, let the weather-wars commence!

    You say [i]”what can they think of that HiFiSim can’t?”[i/]
    One theory is they are not working with legacy code like AS2012 which may hinder new methods. Opus is starting anew, with a fresh look on how to implement weather? Only way to know is to try both of them, same with the new REX.

  2. Kosta says:

    Possibly you are right. Though the problem is apparently not the old code or weather implementation, it’s the way the FSX works and going around that. At least this is what they all claim.
    But, should any of the two manage to get eye-candy of separate metar stations, like Opus does with the accurate winds like AS does, I’ll be first in the line to buy it, I can tell you that!

    I fully agree with Kosta’s thoughts and observations. I wish AS2012 could depict similar multi-layered cloudiness. Doesn’t come close even @20. But overall I don’t see an alternative to it as of today. Particularly if you’re flying PMDG. I recall HiFiSim worked hard to adapt their wx engine to PMDGs airliners and probably they had to concede a number of trade-offs in the process thereby making their cloudiness depiction a ‘lite’ version

    Kosta, you use the textures of REX?
    If so, what for the sky?

  5. Paolo says:

    Since prior i was using the texture of active sky 2012, can i ask you also which 3D clouds of REX use you?

    Thanks

      I switch those often. Anything that comes under my finger there or I like in that moment. I switch at least 4 times since my last screenshots…
