Cesium is not rendered after reaching level 4 terrain #95

Hello! I am trying to create a global terrain dataset and it seems to be created correctly, but when I try to visualize it in Cesium, after reaching level 4, the tiles are not rendered. This is what I see:

I am using a WGS84 image geotiff (>1 gb) and I am using the latest version of tumgis/ctb-quantized-mesh, which seems to be using the last version of cesium-terrain-builder. And I am executing the following statement to create the quantized-mesh: ctb-tile -f Mesh -c 1 -C -N -n “GDAL_CACHEMAX=4000” -s 4 -e 0 -o /terrain /terrain/t2.tif

To serve it I am using cesium-terrain-server.

What am I doing wrong? Thanks in advance!

Ok, the problem relied on the custom ellipsoid I was using, as this algorithm is focused on WGS84, it was necessary to modify the radius to the ones associated to my ellipsoid and now is working.
