Objects using "attach_to_node" do not appear

[MSFS 2024] Bug Reports Aircraft

1

Version: 1.3.23.0

Frequency: Consistently

Severity: Low/High/Blocker
(Low - quality of life, workflow optimization, rare enough to not impact production, etc…
High - critical but workarounds are available, important feature not working as expected, frequent enough to impact production
Blocker - prevents from working on the project, prevents from releasing the product)

Marketplace package name: Not applicable

Context: In developer mode, attempting to add aircraft part.

Similar MSFS 2020 issue: Not applicable
Bug description: We are trying to attach the engine to our aircraft as an attached_object. In FS20 we use the Attachment method successfully and wanted to bring this over to FS24 but we come across this issue.
When using coordinates (0,0,0) the engine appears at the origin as expected. When adding the node name in attach_to_node it will not appear. Other attached objects exhibit the same behaviour.

We also noticed that default planes use either a blank, or no nodes to attach to.

Repro steps: Add a node name to the attach_to_node line.

Private attachments: Sent 2020 and 2024 PackageSources along with instructions.

I don’t know if it is connected, but the modelNode = "" in navigation_graph.cfg files has the exact same problem. It will move the “pin” icon to the correct location, but the attached object will stay at 0,0,0.

just to be sure, the node you are trying to attach to is in the parent object and not another child attached object ,correct?

for example, in an attached_objects.cfg

[MERGE_MODEL.0]
merge_file="random.gltf"
merge_to_model = "exterior"

[sim_attachment.0]
attachment_root = "SimObjects/Airplanes/test/attachments/test/test0"
attachment_file = "model/test0.xml"
attach_to_model = "exterior"
attach_to_model_minsize = 0
attach_to_node = "A_node_in_parent_object" 

[sim_attachment.1]
attachment_root = "SimObjects/Airplanes/test/attachments/test/test1"
attachment_file = "model/test1.xml"
attach_to_model = "exterior"
attach_to_model_minsize = 0
attach_to_node = "A_node_in_MERGE_MODEL.0" 

[sim_attachment.2]
attachment_root = "SimObjects/Airplanes/test/attachments/test/test2"
attachment_file = "model/test2.xml"
attach_to_model = "exterior"
attach_to_model_minsize = 0
attach_to_node = "A_node_in_sim_attachment.0"

Sim attachment.0 and 1 will work as it’s attaching to a node in the parent object (merge adds it to the parent)
Sim attachment.2 will NOT work since it doesn’t know about the nodes in Sim attachment.0

So if you were trying to attach an engine to a wing, but the wing itself was being called as an attachment in the same attached_objects.cfg, the engine would not show up since it doesn’t know about nodes in other Sim attachments.

If that’s not whats wrong then disregard lol

Hello @SWS-AlexVletsas

@kcgb is right, you have all your attachments at the same level and used by your preset.
But the preset doesn’t know about the attach_engine node, only your airvan_exterior attachment does, since that’s where the gltf is located.
That’s where you want to attach your engine, airvan_engine needs to be a child of airvan_exterior.

We will review the documentation to make sure it’s clear, and will see if a console error can be added when the node is not found.

Regards,
Sylvain

Thanks @kcgb and @FlyingRaccoon that solved it. A console message would indeed be helpful.
I suggest:

Sim attachment.X - Could not find attachment node, spawning at origin

Details:

Folder: simobjects\Airplanes\Attachments\MyCompany\MyChocks
File: attached_objects.cfg
SimAttachment 0 "attach to node" specified a node that does not exist in model "MyChocks". Verify that the node exists in the model.

Or something along those lines. :slight_smile:
