I'm using a glb... but it's coming up 90 degrees to the left ?!? how may I  
adjust it 90 degrees to the right?

Thanks,  
Robert

Hey Robert,

Load a gltf model with [Model.fromGltf](https://cesiumjs.org/Cesium/Build/Documentation/Model.html#.fromGltf), and if the rotation is still a problem, try specifying the [rotation matrix](https://en.wikipedia.org/wiki/Rotation_matrix#In_three_dimensions) in the optional modelMatrix option.

Thanks!

Gabby

It’s possible your model is Z-Up while Cesium expects models to be Y-Up. In addition to Gabby’s suggestion, Model.fromGltf has an undocumented option to specify the up-axis when creating it, just pass in upAxis : Cesium.Axis.Z as one of the options.
