Bug description:
Animated decals in MSFS 2024 seem to create a “duplicate” decal mesh of some sort, as if there are multiple instances of the mesh model, when there are not. For example; with an animated decal over the front cargo door, when the door is opened, the decal animates with the door just fine — however, the sim seems to yield a second “duplicate” of said decal that does not animate with the door.

And photos below attached from the default CJ4 livery for reference;
Aside from my livery and the default CJ4 livery, this behavior is exhibited across a multitude of other default aircraft in MSFS 2024… After consulting elsewhere, someone mentioned the following;
I had this same issue and it took me the longest time to figure it out. I had a livery decal model that was only for model.airframe but inside the airframe attachment, I had multiple models in the same directory. In that case, the livery model was applied to each of the sub models. To fix it, I just separated each model into it’s own directory and each one has an attachment.cfg with unique tags.
Your problem might be different but inspect all your tags and consider if the livery stripes can get duplicated onto more than one attachment model.
Considering this, I went and dug through the CJ4 in the VFS and found that while there were no instances of multiple different models within a single part.xxx of the relative parts, there were instances in which different parts shared the same tag, such as part_exterior_fuselage and part_exterior_dirt, which share the fuselage tag. Granted, I am not sure if this is the root cause here or not, but nonetheless, this issue has been present since the launch of MSFS 2024 and is a blocker for animated decals, both in third party applications, and in default core-sim aircraft applications.
What the fix is, I’m not sure, but undoubtedly a fix or alternate workflow would resolve this across the host of default aircraft/default liveries that exhibit this issue.
Repro steps:
Repro Option 1
- Create a mesh livery/decal, parent it to the base-aircraft’s animation empty for that node, and view in sim.
Repro Option 2
- Look at either my example decal livery (file attached below), or look at the default CJ4 blue stripes livery in sim.
