Improved FLIR System still hit and miss

[Viper 13]

The Improved FLIR System is still hit and miss depending on which units are used in the mission
Some units show up well in IR however some are still almost impossible to see
In the following example the Shilka, SPAAA ZU-5-2, and SPAAA HL with ZU-23 are visible in IR 
Unfortunately the AAA ZU-23 Emplacement,  SPAAA Zu-23 mounted Ural 375 and Truck Ural-375 are almost impossible to see

DCS 2.8.4.38947 Open Beta MT
ME Setting "COLD AT START" not selected
Alarm state high

I noticed the same with the S-11 TELAR launcher. Very difficult to see, despite them being clearly active, considering they shot at me with the search radar destroyed.

This is very real, and I have been encountering this constantly.  Pretty much have to turn on markers now if you want to use your FLIR to find some targets.

I'm having this exact problem in the F-15E. Just played a mission in NTTR. T-55, M113, BMP-1, Smerch, trucks... All almost impossible to see regardless of BHOT / WHOT setting

The truck is a Ural 4320T, and it is completely invisible on the TPOD screen, not sure if this is a pod issue, an issue with the truck, or the F-15E, or something else.

This is a moving vehicle not a static, if that makes any difference.

It's not invisible, but it's hard to spot.

[Capn kamikaze]

The BTR80's nearby are far easier to spot, both are cammo'd, but ok they're hard to see, not invisible.

However compared to other similar sized vehicles, in the same setting, it doesn't make any sense that one would be so easy to spot and the other not so, infact the BTR-80's should have been harder to spot, their camo was closer to the surrounding terrain than the trucks, the trucks in this are in their green camo, the BTR's are in a desert camo, yet they're easier to spot.

[Capn kamikaze]

I would expect to see the truck much easier.

[Capn kamikaze]

It looks like the trucks don't have any heat map from their engines, while the BTR's do...

@Capn kamikaze It can happen if they start cold. Can you please attach a DCS track?

It can, but that really isn't how IR works. Just because 2 objects are at the same temperature doesn't necessarily mean they'll both be emitting the same amount of infrared radiation (which is ultimately what infrared systems "see"). This is because different materials and different surfaces have different emissivities and reflectances, which will change how much infrared radiation they'll emit or reflect even if they have identical surface temperatures.

FLIR

We have recently been developing infrared (IR) textures for ships, deck personnel, and more ground units. This required gathering and analysing various references. As a result, we created IR textures for units that correspond to engine locations, exhaust systems, electronic devices, and weapons. They will have the ability to noticeably heat up and cool down based on operation. Authentic IR maps have also been developed for the DCS: Supercarrier deck crew, where the thickness of clothing, equipment, masks, and human body heat are considered. Please stay tuned for more news on this subject soon.

I reported the same bug in April however ED did not respond to my bug report.

As you can see in the screenshots the SPAAA ZSU-57-2 shows up hot on FLIR while the following units in my test mission are missing their IR Textures
Truck Ural-375, Refueler ATZ-10, and AAA ZU-23 Closed Emplacement.
While the units updated to the new system look great, sadly all the unfinished units are left almost impossible to see.
