first of all, congrats for shipping Cesium 1.2, it rocks!
I’ve been using the hosted COLLADA-to-GLTF converter to create glTF models out of some COLLADAs I have. Unfortunately, all show up as black inside of cesium.
Here’s a converted model: http://www.filedropper.com/test_46
Moreover, is there any way to make the converter work localy, without the need of uploading? It gets pretty frustrating when you have to do that for many models!
