Which version of collada2gltf is used on cesiumjs.org/convertmodel.html?

We want to convert COLLADA files to gltf and found the collada2gltf.exe tool.

The problem is that the build of this tool downloaded from https://github.com/KhronosGroup/glTF/wiki/Converter-builds gives us unexpected results (for example: in most cases no glsl files are created). We also tried to download the latest source code from GitHub and create a build ourselves. It compiles fine but this build generates json files with 0 bytes.

When we use the online tool hosted on this website, everything seems to work fine: http://cesiumjs.org/convertmodel.html

So my question: which build are you using and which configuration?
Could anyone give us the build behind this webpage? Thanks in advance.

We recommend just using our web-hosted version since we will always keep it in-sync with the latest version of Cesium. I believe it is using a ~1 month old version of COLLADA2GLTF built on Windows. As far back as this pull request merge should be OK. Submit issues specific to COLLADA2GLTF to its github repo and they usually get attention quickly.
