old version is ok

2

What problem are you seeing exactly? In which version? And which version worked?

3

worked:

FileVersion: 3,
Version: 28,
VersionName: 1.14.0,
FriendlyName: Cesium for Unreal,

not work:
{
“FileVersion”: 3,
“Version”: 39,
“VersionName”: “1.23.0”,
“FriendlyName”: “Cesium for Unreal”
}

You still haven’t told us what “not working” actually means, though. 1.14 to 1.23 is a big jump, too, so it might be worth trying some version in between to determine more precisely when it broke.

5

col:323
tileSet.url = getAttributeString(pTileset, “href”)
.value_or(std::to_string(tileSet.level));

if href is empty.It is not work.

Your tilemapresource.xml looks invalid to me. It would be fine if the href property of <Tileset> were missing entirely. But since it’s present, it shouldn’t be blank.
