Polygons not being rendered on the surface created by the elevation matrix

[Witellsteim]

Hello everybody,

I was recently trying to render polygons representing buildings. The problem that has arisen in the process is that those polygons are being rendered on a solid baseline, which is determined by the lowest point in the elevation matrix. This means that the polygons of buildings that stand on a hill or higher point are rendered below the surface instead of on top of it and - if their height is not sufficient - they disappear into the ground.

Here is my question: Is there a way to render polygons on the surface created from the elevation matrix? (Am i just missing something?)
If not, this can be considered a suggestion for a new feature.

Kind regards,
