Colour Filter Applied to Australia

Hi Team, We’re wondering if there is a way we can pull the imaging and Colour
filters used in sim into QGIS. This would help to correctly colour match
without the need to do a full sim export to check if the blend is correct. We
took the image from bing and overlayed our capture and matched the bing colour
however with the filter that is applied over the imaging in sim, our image
doesn’t match. Being able to do this would be extremely helpful!

Hi Team, whilst terraforming today I seemed to have glitched the sim causing
the Red mask to be “Removed” temporarily. Our scenery looks so much nicer at
the realworld colours. Is there a way we can exclude the mask from sceneries.
I’ve attached two photo’s One with and one without the mask. With Mask:

Without:
As you can see it brings the
scenery together and really makes this area look accurate. The red tinge over
a massive part of Australia, in several areas such as this one it is not at
all the case. Look forward to seeing what we can do here.

Hello @ImpulseSimulations Where did this
happen? It this your own aerials or the game ones? If you are able to repro
the color change when using the terraforming tools, I’m interested to know
how. We are reviewing this post so I’ll come with a proper answer later on.
Regards, Sylvain

Hi @FlyingRaccoon I have been able to
replicate the removal of the red mask that was applied over Australia several
times. To reproduce simple create a Rectangle with a height map then edit it
and click and hold the Flatten or Smooth tools. Eventually you’ll be faced
with a window to say you’ve been disconnected from the servers (internet
issues) if you push past this and eventually it comes up again once closed
after that if you move away from the area either via Slew, Dev cam or drone
and return to the area it will be what I can only assume is the RAW Bing data
in a much more accurate form. The area in particular from my photos is Bendigo
Airport (YBDG) having the ability to remove the mask would allow us developers
to use our own CGLs much easier as we can match them to the Bing imaging which
tends to have much more colour in it over this red mask. Also note that if the
area is covered in a custom Aerial the mask is not there but if we were to do
that for this area to cover what we would need for the area to look nice It
would be above 5GB without a doubt. Look forward to seeing what we can plan
for this.

Back in the early Alpha version of the game I believe someone complained
Australia was “too green” so they put a red filter over it and completely
broke Australia and we have been stuck with it since.

It’s like when someone said “the music is too loud” so instead of setting the
default music slider to 50%, they reduced the maximum music volume. Now if I
want the music louder I have to turn everything else down.

Hello @ImpulseSimulations
@Nick_NZASimulations " I believe

" That’s not really the explanation
obviously. We have two types of color correction: - Aerial color correction:
imagery color varies from one tile to its neighbour, and from one LOD to the
next. To fix this we have to apply a color filter on aerials so that they are
uniform and you don’t see any discontinuities while flying. That’s what your
picture are illustrating above; the aerial ends up being colored in red to
match high neighbouring tiles and higher LODs. - TIN color correction: TIN
colorimetry is most of the time very different from the aerial. TIN is
Australia are a good example of this. To avoid any discontinuities, we apply a
color filter computed from the aerial on the TIN to better match the
surrounding aerials. Here’s an illustration of the difference at the border of
the TIN at Adelaide: Raw:


Corrected: Now, why are you
ending up with raw aerials when editing heightmaps? Thanks to your great
feedback, we identified the issue. The game has a mechanic where it will
switch offline if it hasn’t received any signal for a period of time. I think
you can witness this if you click on the main window border for over 30
seconds. This is not supposed to happen when clicking in the Scenery Editor so
we will have a look and fix this. When switching offline, the game is supposed
to clear the terrain data and switch to the procedural rendering. Since we’re
not in the correct flow here, this does not happen and you end up having the
tiles already loaded being rendered without the aerial color correction.
Regarding your first question. No, giving you access to our imagery is not
possible but we have plans to improve how the Scenery Editor lets you decide
how this color correction process influences your scenery. Finally, we are
aware this color correction process leads to cases where the raw aerial is
better than the corrected one but we have no choice if we want to maintain
image continuity between locations and LODs. The way to improve this is to get
better source imagery that needs less correction and improve our color
correction processes. That’s something we want to improve in the future
obviously. I hope I answered your questions. Regards, Sylvain

I guess the problem is it effects a lot of things including airports … this
is NZA YMHB with true black material runway grime. It gets tinted red as well.
Here is what it use to look like vs it what it looks like now, the red hue
happened several sim updates a go. Will be really nice to be able to control
and we’re glad its being worked on.


Thanks for the explanation here
@FlyingRaccoon, however that doesn’t really
help me in this case much. What I am asking is, if there is a way us
developers could exclude the filter around the area that our airport/scenery
is being developed around. Most of us have access to tools for a custom CGL,
however as my last 2 weeks have been manually editing our aerial to suit the
area I am hoping that there is a possibility for some form of exclusion tool.
it brings so much more life to the area and helps us to be able to match the
aerials that we have access too which are generally much greener. Look forward
to hearing more.

That’s one of the issue we plan to address by changing the default behavior
and available options in the Scenery Editor. By default, the “Enable
coloration” which allows you to override this color is disabled. You probably
want to use it to make sure your airport is no longer impacted by color
correction.

No, you can’t disable it. The only way around this would be to cover the area
with your own CGL or TIN.

@FlyingRaccoon problem appears to be even when
using that in an area covered by TIN, the colour refuses to return to the way
we have it set currently as apron override. For example, if you test our
release of Adelaide International (YPAD) you can see if the World Update for
Australia is not installed our aprons look as intended per our release. Then
if you install it, it’s a completely different look. The point in these
photo’s is the colour change in aprons even when using colour override.
Disregard the change in colour of CGL that was fixed with the Tin Exclusion.
With World Update Australia Installed:

Without World Update Australia
Installed: As you can see even
though in both photo’s, the aprons are using custom colours via the colour
override it appears that the colours from the nearby photogrammetry, although
TIN excluded still seems to effect our aprons.

I’ll also add that within Australia it is common to have Yellow sort of long
grass, if the area has more heat, and the sim will not draw grass unless it’s
closer to green. so any area, that is colour matched closer to the Red Hue
won’t draw the grass either.

Oh you actually have custom colouring enabled on those runways and aprons? Do
you also see the problem when editing the project in the Scenery Editor?

Yes, I see it everywhere, seems that the biggest culprit to our currently
faced issues is this red mask. I Sent our project files in our Teams group if
you have access to that? Otherwise I can upload a release build or dev files,
whatever you need. :slight_smile: Thanks for looking into this.

Ok I see. The TIN color correction is still playing a role in some cases when
“Enable correction” is enabled. It seems to depend on the source material as
well and darker materials are more impacted. We will definitely have a look at
this.

Great to hear, thanks for that. Please keep us updated.
