Hello, i'm new in FME. I don't know how to transform .rvz BIM data into 3d-tiles cesium.js format. I use FME-revit plugin to convert the .rvt to .rvz. Next, I add a reader in FME to read the converted .rvz data(IFC). Then i add a transformer(writer) to write the data into CESIUM3DTILES format. But the translation failed.
