Prepar3D blue haze

Recommended Posts

When I installed 2.5 I loved the blue haze that showed up on the Rex 2 and 3 weather themes.  When I added REX Texture Direct, it was gone...replaced with a gray haze which I thought looked far less realistic and crappy.  Does anyone know what the blue haze file is?  I was thinking to back it up outside of REX so that I could overwrite that one file after I applied cloud changes.

 

Thanks!

Weird...I had Rex 4 texture direct installed and removed it because I hated that blue haze and couldn't find a way to get rid of it otherwise. Way overdone in my opinion. Sorry, I'm not much help. I'd actually love to be able to replicate your "issue" :)

Sorry, I am with Gregg. I was always wondering why the heaven around me is all gray while it looks blue out of the window of my room. Obviously it's REX Texture Direct 4 which I use indeed.

 

You can influence this using monitor settings/calibration within limits, but then you may end up having blue houses, streets and planes all around.

 

Kind regards, Michael

No I get what you guys are saying. There is an xplane plugin called real terra haze that does an unbelievably good job atmospheric scattering and haze effects. I'd love to see P3D nail that effect better.

Hi Gregg,

 

Have you tried restoring your default or previous (REX2/3) sky themes? Apart from sky textures, the "sky_[...].bmp" files in \Prepar3D v2\texture\ also contain a number of pixels that determine light/shadow colors. Perhaps they also determine the fog/haze color? The image here explains the meaning of the pixels for FS9/FSX, but it should be good for P3D as well:  http://www.cat-tamer.com/flightsim/atchmnts/environment_pixels.jpg

Maybe...but...it only shows that blue haze on 2 weather themes.

I posted this over at the Rex Texture Direct support forum and thought it would be good to post it here so folks could see the results...

 

Yes...looks like it's tied to the sky texture.  I spent some time loading quite a few of the textures and it's pretty amazing how different the sky and weather looks in some of them.  The haze effect on each of these is starkly different.  You don't pick that up in the previews.  

 

I've embedded the images below but it may be easier to see by looking at the full album on imgur.com

Thanks for taking the time to test this. It looks like the bottom row of pixels determines the haze color, it'd really be great to have Shade 2.0 to manipulate things like this more easily... :wink: Which set did you choose in the end?

And here is my response on our forum:

 

But isn't that the point of having choice? It would be very odd to have different hue values for haze vs. skies etc. Understand there are many values built into the sky textures, change one and it could off the rest of the scene. 

 

At any rate, we are working on a major update with Texture Direct (SP5) and it might just very well make you happy, as well as something we cannot yet discuss in development. ;)

Sorry, I'd started this thread before I posted over at REX and thought it would be a good idea to update folks here since many were interested.  My point, not well stated, is that there are some skies that have more haze, and gray haze at that, than others and it's important to choose wisely.  This was an interesting exercise and the pictures are well worth keeping around so that, if you want to change haze, you can do so by looking at them.  BTW, these look A LOT different in FSX which, to me, has always looked overly hazy (my opinion).  In P3D they look much better. 

 

One thing that had me thinking is that it might be nice to select a set of textures that you like from Texture Direct and have it load from the set based on atmospheric conditions and location.  Not sure if that's doable but it would be A HUGE change for simming!

At the moment I'm still flying the default, but I liked Countryside, Misty Sea and Death Valley.  Polluted reminds me of the East Coast summer so it looks good as well for some circumstances.

Last I remember is that you were on 2 other beta projects and I never heard back since. Contact me on our forum again and let's go from there.

I like the ability to generate weather according to the airport code.  But I wish there was a way to select only those part of the them you want to change...based on the generated selection.  Maybe some selection boxe or such so that I can check those parts that i want to apply to the current theme.  That ould be great!

I see you have posted your feedback in our 'suggestion box' on our forum, thank you for that! I hope others follow as it's a great way for our developers to keep track.

Looking at my screen caps again this evening, it's interesting to note that in some of the screen shots, you can't even see mountains that, in another screenshot, you can see fairly clearly.  Perhaps this is a clue to why vis has always seemed short and hazy in FSX to me.  Having worked in a tower in the military, years back, I have a pretty good idea as to what a 20 or 30 mile visibility day looks like.  Sometimes I look in FSX and think...lord, it's hazy and I look at the vis and it says 25 or more and I scratch my head.

Hi Tym,

 

I was looking at those sky bitmaps and I noticed there are 10 of them for each time of day.  Do you know why there are 10 of them?

Usually in real life the sky horizon is more of a very light neutral color and the landscape horizon definitely more bluish. If you have a blue sky horizon then that effect isn't seen as well and doesn't look as realistic. Even on a gray overcast day the blue horizon mountains really stand out. Check out Rise of Flight to really see it in a sim. I can't seem to replicate that with REX. The closest I have seen in FS are Pablo Diaz's textures and Flight Environment in FS9. I have a chart showing how the colors are assigned on the sky textures, but don't want to go through the hassles of posting (used to be easy). Anyway the bottom two bars are for high and low horizon.

I had the same problem for a while, but I disabled the volumetric fog in P3D and it seemed to fix it. It seems to me to be way overdone. OPUS does a very nice job of adding haze at the horizon, but it's not overdone. I also have REX OD+TD+SC so I know your frustration. As far as I know, it doesn't have anything to do with REX.
