There are basically two sources of the error for a “wrong height”:
- The source data of the model may contain the “wrong height”
- The data in which context the model is displayed has the “wrong height”
(And the term is written in quotes, because the height is always “wrong” in one way or another - see What is the shape of the earth? for details)
So the first question is:
When you tile that data with the additional CRS information, can you still use the “Adjust Tileset Location” functionality? If this is still possible then you can adjust the height there.
Otherwise:
Are you using a certain terrain model for the visualization, like Cesium.Terrain.fromWorldTerrain?
Otherwise:
You can still adjust the tileset location (height) manually, by assigning the proper tileset.modelMatrix. This is similar to what I wrote in the other thread - fetails can be discussed when necessary.
