3D Tiles: Lines visible under building, how to hide them?

CesiumJS
1

I’m drawing a line through a 3D Tileset (a building from Cesium Ion). I made the building almost fully transparent:
tileset.style = new Cesium.Cesium3DTileStyle({
color: ‘color(“white”, 0)’
});
However, the line is visible under the building.
What I’ve tried so far:

Using a very small opacity (0.01)
Using clipping planes
My goal: the building shouldn’t remain visible, but lines inside or under it should not be visible.
How can I achieve this in Cesium? Is there a way to use a “mask” or another approach for 3D Tiles?

Hi @David_Plitnizki, how is the line defined? Is it a PolylineCollection or similar, or is it another 3D Tileset?

If you can share a Sandcastle example demonstrating the issue, it could help us brainstorm faster.
