NE UK too orange

Recommended Posts

Hi

I have had the uk version in prepar3d and was very happy with it. Have just installed the new version into prepar3d v2.3 and am flying round Liverpool and the splash lighting is far too orange. Originally it was like the screen shots on the aerosoft site, much more yellow/orange. Now it is really orange. Any ideas why?

 

Regards

Chris

Hi Chris, thank you for posting in our support forms

the ground splash textures were not replaced in v1.1

its just our models and their textures

with that said P3D v2.3 does present night colors slightly different than FSX

 

i haven’t had the chance yet to go through advance environmental settings in P3D

as i noticed the differences too; and was slightly bothered by it

since both FSX and P3D share the same ground splash textures

this is why i am convinced this is P3D settings somewhere

Hi chris

I'm sure it is either a setting or something in v2.3 as I had it running in 2.2 but stopped using it until the issues were sorted. Last night I redownloaded the new version and started using it again. It is great apart from the light splashes which seem far too orange and not the softer yellow shown in the screen shots and how I'm seem to remember it being when I previously tried it. If I get chance I will post some screens.

 

Regards

Chris

this issue is only under P3D right?

you’re not having any color imbalance under FSX

Thank you Chris,

i think this is an easy fix;

 

to get the natural color tone we are used to from FSX

i recommend turning off HDR!

 

did you try introducing the following parameters into your p3d.cfg?

[GRAPHICS]
DAY_THRESHOLD=32768
NIGHT_THRESHOLD=0

I tried turning off HDR but it didn't make any difference.

 

I haven't tried that change, what does it do?

the added param allows you to indicate your day time threshold as well as night time

you’re scale runs from 0-65535

where's 65535 is the brightest and 0 is complete dark

if you wanted more light during your night flights

a NIGHT_THRESHOLD=4096 should do it

or if you prefer pitch black night a 0 is the right way to go

 

i came across this little article

i run a short test and found it does effect the area we are concerned about

but... i haven’t spent enough time yet to determining what the correct values

or if there are other params that should be adjusted

but it’s a great start http://forum.avsim.net?showtopic=451055

focus on post #3 info to start with

Hi Chris

 

I tried a few of the parameters listed in the thread but they don't seem to tone down the amount of orange. It is a shame because it definitely didn't used t be like that. I wonder if it is to do with the various lighting issues in the current v2.3, hopefully might be fixed in a later version.

Hi Chris

i have done some experimenting with the params as well;

i haven’t nailed it down yet, but we are on the path; i shoot an email to LM

im hopping they will point us in the right direction shortly

 

i could be wrong with the following statement

i believe this parameter is our main culprit

"Approximates luminance from an RGB value"

im not sure how to manipulate the formula yet

Hi Chris

i have been in touch with LM in regards to this issue

i haven’t heard back as for a viable solution yet

i was hoping for a cfg change that will get us back to normal

but it seems it little more complicated formulation that relies on many other factors

i believe they are revising for the upcoming update

Hi Chris

 

Any update on the amount of orange light cast on the ground introduced by Prepar3d over FSX?

 

I have taken to disabling level 0 for the time being as that gives pleasing results but minus the light pools on the ground.

 

Regards

Chris

Hi Chris; i am too eagerly waiting for the fix

from past experience working with LM; at this point i can almost safely say we won’t have a "dedicated patch" released before their next revision; i do believe our issue will be resolved on P3D next revision release (2.5)

 

the problem has been identified,

it is RGB to sRGB conversion formula they have been using that messes up the night colors

this is also the case with regular night layer for any existing photoreal package

Chris,

 

I am interested in those Day and Night Threshold statements that you mentioned further back in this thread. Do these change the overall light levels in P3D (day and night)?

yes these still hold true in P3D

i have tried these out; but they do not change the color issue we're seeing

 

these settings are very straight forward;

they control the darkness or brightness of the day/night in fsx itself

normally winter nights are crisp darker then summer nights

these variations allows you to manually set a darker/brighter night or day

 

here is the SDK article about this for P3D

here is the SDK article about this for FSX

That's very interesting information, Chris. I asked this question several times over the years with respect to FSX, and never got an answer.

Over the last decade, I've found many parts of the UK have developed an unnatural orange glow, particularly at night in the vicinity of drinking establishments. That and Scouse brow :lol:
