I think 3D Tiles Tools is meant to run with the 1.0 version of glTF pipeline, unless you’re using the 2.0 branch ([https://github.com/AnalyticalGraphicsInc/3d-tiles-tools/tree/2.0-tools/tools](https://github.com/AnalyticalGraphicsInc/3d-tiles-tools/tree/2.0-tools/tools)) which I think is still experimental.

So updating gltf-pipeline separately might be a problem. The other thing is that by default running something through gltf pipeline should automatically convert it from glTF 1 to 2.

Does downloading a clean copy of the 3d-tiles-tools repo, running npm install and then running optimizeB3dm not work for you?
