Why the parameter -l for ctb-tile is missing?

Hi @Hisos, you have to use this PR, the master branch does not contain the QuantizedMesh or -l flag support.

Or you can use this Docker image, it already contains all of these capabilities.

Hi, @ahuarte47. Do you have a small dem.tif converted successfully by your program? I have tried several dem.tifs, the conversion is ok, but the cesium failed to load the data: "An error occurred in "CesiumTerrainProvider": Failed to obtain terrain tile X: 1 Y: 0 Level: 0.". I tried another software named cesiumLab for the same dem.tif, and the .terrain is ok for cesium. I tried preprocessing the dem.tif by ArcmAap to deal the NoData=0. I tried "-f Mesh" and "-f Mesh -l" or not. All the ways is unamiable for me. What a headache, haha.

Do you have defined the Content-Encoding: gzip content negotiation header?

That's GZip. CTB defaultly gzips the data, Most of the blogs don't mention us of this. So I was confused why the cesium loads terrain failly. That will be ok after the web server defines the Content-Encoding: gzip. Thanks again!
