FLIR Screen totally black-white after bomb explode

This lasts for a little bit though. Ok, not half a second, but the picture returns fairly quickly. In DCS, as long as there's smoke and fire, there's either a blob or the image is over saturated, even with auto gain/level enabled. The saturation is normal for fixed gain/level, but auto is supposed to adjust these automatically, in order to maintain the darkest and brightest parts within the visible scale (within reason, maybe it'll try to contain 90% of the range it sees, depending on the scene). I have FLIR cameras (not targeting pods, but FLIR is FLIR) at work and they work like that.

 

 

Even then, the FLIR cameras found in current commercial products are definitely not the same as a FLIR imager from ~2005. It will generally washout because of the same limitation of any camera: "exposition" time. Sure, using dual-image techniques (think they call it HDR) can help, but even then... And that's something available in current day smartphones, not a FLIR pod from 2005.

 

 

Even from the videos, you can see that this washout stays for quite a long time, suprisingly so, while the flash is almost instantly gone when viewing the CCD images.

Watch the videos again. In WHOT it flashes white on the explosion, then the residual washout is a black background against white smoke. In DCS, if you look at smoke when in WHOT, the whole screen goes white when it should be dark against white smoke.

The FLIR whiteout / blackout in DCS is NOT an intended effect, it is a shader bug likely introduced with deferred shading (2.5). It effects multiple modules A-10C, AV-8B, etc. and also depends on the smoke colour used i.e. for marking targets.

 

It can make night missions impossible as, after the first explosion, the area can be impossible to view for several minutes (5 ?) and you may not even know the area is obscured as the FLIR image remains blank.

 

A work around is to

 

• set "Smoke chimney density" to 0 and restart DCS

 

... the FLIR bug can also "fix" itself temporally if running several consecutive missions in the same DCS session i.e. playing a replay file several times.

Happen to me from time to time (chimney is set to 5).

 

My hotfix : delete fxo and metashader2 folders in saved games\DCS and restart.

 

To be sure it's fixed I launch the A10 quick mission and blow the first truck with a mav.

 

Fix works 90% of the time.

 

PS : using old nvidia drivers 442.74, don't know if it changes anything

It'd be normal for the image to get saturated for maybe half a second. Right now, the smoke looks like it's a huge and constant heat source, while this is not the case IRL. The sharp temperature difference between the momentary explosion and the surrounding environment is enough to saturate the sensor before it can adjust, but the subsequent smoke or fire is definitely not hot enough to do that.

 

 

I flew on OB prior to today's patch but after the 10 June patch and besides seeing the DDI disappear when back lit by the sun I also saw this anomaly on the Mav F FLIR video. My buddy had a smoke marker at a base and any time I pointed the seeker at the smoke the ENTIRE page would turn completely white as if it was looking at a huge heat source. Moving the seeker away from the smoke would bring the video back to normal. This kind of issue was also seen but to a lesser extent if I was trying to target in the area of something that had just exploded.

 

This wasn't an issue prior to the 10 June patch and no I'm not running mods. Made targetting vehicles a massive PITA though.

IIRC, it's an issue with some smoke markers only. Green is OK, but red has this problem, at least on my system. I just stopped using red markers on my missions, for now. Was your smoke marker red?

Hi everyone,

This bug is more than a year old and considering ED's policy, we're going to have it for a long time to come... the only reaction after several reports of this bug is that they will wait to develop the new FLIR engine... and you know what?.... I'm ready to bet that the bug will always be there with the new FLIR engine... because it feels more like a smoke shaders problem than the FLIR engine itself... and since ED specializes in adding new features to buggy stuff, I think we're still "laughing" for a long time.

Personally I think it's a shame... it's been reported for more than a year now, the community has done a lot of the work in determining which version the bug came from, that it's because of the smoke, that before 2.5.6 (or 2.5. 5) we could fix the bug by setting the chimney fumes to 0 but not anymore... we explain that it's still a bit "game breaking" when at night we can't target a zone anymore, but no we'll wait another year (or more when we know that the new FLIR engine is in low priority)...

This means that we have to fly during the day to make sure we have the CCD image as backup in case the FLIR image is buggy.

But nothing... nada... we'll wait to develop the new FLIR engine and we'll see... a shame! :mad::mad::mad:

I have no solution, fxo / metashaders removed, the chimney is closed at 0. The problem is that there can also be dazzling colorful smoke of JTACK , once blue, once red, it all depends on the time of day. As soon as the smoke is in the TGP range, the screen turns completely white.

Indeed there's no solution … totally random bug… and set the chimney smoke to 0 was a good fix before version 2.5.6.

A missile smoke trail can turn the FLIR screen totally white.. I have the case with a AGM122 in the Harrier :hmm:

As long as it is hot down I have no clear view, but when I zoom out this is only restricted to the area where hell just break loose. Will further try to reproduce. (I have set chimney to 0)

Clearly the "Good FLIR" image as posted in this thread is no better. It doesn't washout at all.

 

 

Maybe there are issues with the current rendering (including the washout being sometimes the same "color" as the explosion), but the "good" image is clearly not realistic at all. It should absolutely washout and stay like that for some time.

Can you show me some screenshots of what you are seeing in this instance? A track as well so I can make sure I am replicating just as you see it. Right now I don't see this type of issue.

Harker asked me about the smoke color so I very well could be off on not happening prior to patch as the MP servers I fly on don't use smoke thus that part might have simply been the red smoke causing it. Odd that smoke would do that but when I moved the sensor over the smoke it would go totally white and I could reverse it by moving the sensor away from the smoke.

Here is a typical AGM-65F example (it is similar to the TGP FLIR issue).

Clearly the "Good FLIR" image as posted in this thread is no better. It doesn't washout at all.

Why should it, according to the TGP FLIR image, the smoke is COLD (Black is HOT, White is COLD), yet the warm light background is now dazzled/overexposed by the cold white obscurant.

Note: this image is different to the previous IR Mav image which was using White Hot (with black cross hairs)

In my videos it looks exactly the same in TGP Flir as in your AGM-65F Flir. Red smoke dazzles TGP FLIR, depending on the time of day, it may be blue smoke. The smoke coming from the fire (heat) should be more dazzling than a smoke candle.

Note: This is what it looks like if I play the track a second time - restarting DCS but not my PC i.e. the smoke renders correctly (the IRMav's cross hairs are invisible because they were set to be black, to show up against, what was, a white background).

... this is the same render behaviour as I found with the TGP's FLIR.

Render Bug seems related to the temp folder contents.

 

FLIR/IRMav Render Bug seems related to the temp folder contents.

 

To see the render bug, before starting DCS :

 

• delete the contents of "USERNAME\AppData\Local\Temp\DCS"

• Run DCS

• View my previous track

 

To see normal render:

 

• Exit DCS to Desktop

• Restart DCS

• View the same track, note how the smoke/scene render changes and the vehicles are now clearly visible.

I didn't catch the procedure to get it to work properly. Can you expand? Thanks

No problem.

 

Run DCS and play a short track file that displays the issue i.e. my IR Mav track.

 

(not sure if it does it for the first play or needs a second play as well)

 

Exit DCS to windows desktop (important).

 

This will leave some temporary files in "USERNAME\AppData\Local\Temp\DCS"

 

Start DCS a second time and play the same track file, the IRMav IR image will play back correctly due to the presence of the temporary files.
