Problem wih first lod level not writting tilles splitting stage

[AdrienHoule]

Hi, so I made a simple sphere with a material on blender, and subdivided it a lot.
The decimation level seems to be working, fine but when I reach the splitting stage, the first LOD of my object just writes no tiles, but the other ones are working just fine any idea why ?

Same issue here using the latest v1.0.13 and OSX and Blender 4.4. The resulting tileset.json seems to be empty then too. The test model from readme (https://github.com/DroneDB/test_data/raw/master/brighton/odm_texturing.zip) however works well.

EDIT: After some more testing it appears the splitter requires triangulated faces while the decimater does can handle quads. As the original model is used for LOD 0 splitting, it fails to load there without any warnings other than "Loaded X vertices, 0 faces in Yms" message in the log.

So the solution is to make sure used model is triangulated.
