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](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](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](https://github.com/KhronosGroup/glTF/pull/246) should be OK. Submit issues specific to COLLADA2GLTF to its [github repo](https://github.com/KhronosGroup/glTF/issues) and they usually get attention quickly.
