Visible Markers for LandmarkLocation Objects?

I’m adding points of interests and cities into my scenery. I used the LandmarkLocation object to define these landmarks. I haven’t found any content on how to make them visible to the pilots. I do know that they will show up on the World Map, but I’m more interested in the pilot seeing them if they have visibility turned on.

I did a chatGPT query and it mentioned adding more attributes to the XML tag. It sounds logical, but whenever I run the build I then get certain errors. Overall it looks like a parsing issue:

ERROR: line=1966, col=304, The attribute ‘visibleInCockpit’ on the element ‘LandmarkLocation’ is not defined in the DTD/Schema.

ERROR: #C2309 isAirport is NOT a valid token!

ERROR: #C2309 visibleInWorldMap is NOT a valid token!

ERROR: #C2309 visibleInCockpit is NOT a valid token!

Here’s the XML object:

<LandmarkLocation 
   instanceId="{34118FFC-59E7-4D34-91A7-997DBB59DADD}" 
   type="POI" 
   name="Vault Toilets" 
   owner="tabletop ANDROID" 
   lat="39.08932751672920" 
   lon="-109.10380405483563" 
   alt="1323.07721614185721" 
   offset="0.000000" 
   altType="AGL" 
   isAirport="FALSE" 
   visibleInWorldMap="TRUE" 
   visibleInCockpit="TRUE"
/>

It’s clear to me that this was one of those instances were GPT gave me bad information. I can also see that these attributes are not defined in the SDK. Scenery Editor Object XML Properties With that said is there a way to display a marker for LandmarkLocation objects?

Strongly suggest to avoid asking any AI advice regarding msfs code, they were not trained in the documentation

Of course the properties suggested are not recognised, the bglcomp.xsd are not allowed in the schema
(Maybe you can upload it to the AI, and ask her to store it so it won’t suggest allucinantion anymore)

About your issue, I have Landmarks showing correctly,
Try adding distShowMarker property (I have that in mine)
