Styling outline of features in a 3D Tileset

Is it possible to style the outline of a feature in a 3D Tileset with another color than used for filling the object?
I used the color-Property of Cesium3DTileStyle to style the features.

Are you styling the outline using the silhouette post-processing like in this Sandcastle?

If so, that’s an independent system from the 3D Tiles Styling language itself, so you should definitely be able to pass a different color to that than to the feature style.

Not yet, but is this also suitable not for just picking one selected feature but also to colorize all outlines of a feature displayed in the scene?

Yeah, you can pass an array of features, not just a single selected feature at a time.

Okay, thank you.
