Altimetric layer become black in some areas

[Francesco-NovaProject]

Hi,
I'm facing an issue visualizing a survey. The problem is that moving the model in some cases the altimetic layer is like "cutted" on a plane, the cutted areas become black . I thought the reason was the size so I reduced the altimetric area but the problem still remains.
The survey where I face the problem is this: https://www.speleopg.it/monte-maggio/
For example, for this other survey, I have no problems: https://www.speleopg.it/modelli-3d/

Could you please help me understanding where is the problem?

Hi,

Thanks for the report.

This is a bug that is exposed by your model where the cave survey is small compared to the size of the terrain.

The view of the camera has a near plane and far plane, and only objects between those planes are visible. With the error in scaling, the terrain is being clipped by those planes.

I have fixed this in 2.2.1 which now displays your model correctly:

Hi, thanks for the reply, at the moment I continue to use this version so I cutted the terrein and added other caves and the issue seems to be solved. I have another question, as you can see at this link https://www.speleopg.it/monte-maggio the initial view is too close to the model so you can't see anything, you have to zoom out to see the caves. Is there a property that allows to set the initial zoom level?
My actual view settings are these:
view: {
section: 0,
entrances: false,
cameraType: CV.CAMERA_PERSPECTIVE,
box: false,
terrain: true,
view: CV.VIEW_ELEVATION_S,
shadingMode: CV.MAP_OVERLAY,
terrainShading: CV.SHADING_OVERLAY,
walls: true,
HUD: false,
autoRotate: false,
autoRotateRate: 1.0,
stations: false,
stationLabels: false,
fullscreen: false
}
Thanks a lot.
