Hi, I’m currently working through the following tutorial: http://cesiumjs.org/2014/03/03/Cesium-3D-Models-Tutorial/
When it shows the reference frame on the truck sample, the red axis extends towards the right, the green towards the front and the blue axis upwards, as I would expect.
However, when I attempt to use the default models using the Sandcastle, they appear with the red axis towards the front, the green to the left and the blue axis upwards (for some reason, whenever I attempt to screenshot the image the axes disappear).
The issue is that when I attempt to use the 3D model sample to rotate my own model files, that it appears that the rotation of the model is incorrect (e.g. it rolls when changing the pitch variable).
I suspect this might be the cause of the issue as when using my own files created using the glTF converter, it shows the reference frame like shown in the picture in the tutorial, but not when using the default models (as described above).
Could anyone clarify what is the correct behavior and whether I have to modify my COLLADA files to change the axes around?
