Triton hides the geometries

[marcoma9023]

I created a polygonal geometry using a FeatureNode with CLAMPED and DRAPED properties so as to make it anchored to the ground.

With Triton I have the problem that you see in the video, since Triton needs bathymetry, the geometry following the ground will get lost under the water.

I tried to set properties like DEPTH_TEST, but without success. I tried to understand if drawing the geometry or Triton first would change something, but everything remains unchanged.

Ideas?
