At the moment, We’re using the superb BJS Sandbox as a main tool in our work with AR apps pipeline (native and web), as we use GLTF/GLB as the standardized 3D assets format.
The case is that we’ve detected that, in certain occasions, the GLB generated by Sandbox doesn’t work in apps (don’t crash but it shows nothing in the AR layer). Using instead Cesium’s gltf-pipeline command line tool over the same GLTF generates GLB files that always work perfect with the aforementioned apps.
Said that, can anyone come up with any idea about the cause(s) for this inconsistent behavior experimented with the Sandbox exporter? Certainly We’d prefer to use Sandbox instead of the Cesium command line tool, because with Sandbox we have a very convenient bundle of tools all in one.
By the way, are you planning to include Draco compression ability in Sandbox GLB export?
