Hi, currently in Houdini 19.0.383 Python3

What is the best way to get basic geo animations (rotation, translate, scale) from Houdini to Sketchfab?

It seems to me like Sketchfab does not support Houdini's point cache FBX Export process (https://help.sketchfab.com/hc/en-us/articles/208259013-Houdini) ? Any idea when this will be resolved?

I have also tried .gltf/.glb animation using the Labs GTLF Rop, but that doesn't work in SketchFab (despite working in a gltf viewer).

I have also tried using the Sketchfab render rop, but am getting this error:

Sketchfab Rop error:
Error rendering child: /out/sketchfab1/geo_exporter
Error rendering child: /out/sketchfab1/shell1

And diving inside --->

shell1 error:
Python error: Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "labs:river/sketchfab, PythonModule", line 223, in export

hou.OperationFailed: The attempted operation failed.
Error: FbxExporter::Initialize() failed. Error returned: File not created


geo_exporter error:

Any advice would be appreciated, thanks

Update - I have managed to the sketchfab node to output and upload successfully, the issue was that I did not have a material assigned to my geo.

However, the animation is not transferring. Testing with a basic 50 frame scale and transform on a polygon torus. The torus makes it across, but only static.

I'd love to know as well why even basic transforms like scale and rotation of a cube, exported to FBX, don't animate in Windows 3D Viewer. Feel like the issue is linked. Exporting something similar from Blender works fine.
