Why isn't this light and asset in Spoke casting a shadow?

[SeanBannister]

I'm new to lighting 3D scenes (thanks Dom and Jim for last nights live stream), it's raising a few questions. For example the following scene (available here) I've placed a "point light" (also tested with directional light) above an asset that's set to cast a shadow on to an asset set to receive a shadow but I'm seeing no shadow. I was expecting a shadow on the ground plane.

I was able to get shadows to appear in the preview image when publishing to Hubs. I don't believe they are going to show up in Spoke because they need to bake to a texture when you publish the scene. However I'm not seeing them when I get to the Hubs scene - that seems like a bug. I'll see if I can find out.

Check the upper right of the 3d window. There should be a drop down menu where you can change it from ‘Lit’ to showing shadows.

Just trying to get my head around this... when I click the dropdown and select "shadows" it doesn't show the shadow in Spoke but does when I publish to Hubs. But every time you load a scene in Spoke it resets that dropdown back to "lit", so I have to ensure I change it back to "shadows" every time before I publish if I want shadows?

I might be missing something, is this right/bug/or something that needs improving?

This is likely due to an outstanding bug in Spoke: Hubs-Foundation/Spoke#861 We can continue tracking this issue there.

This would be fixed if we could update to the most recent version of three.js. We use a custom fork of three.js for Hubs and Spoke. We can't currently update that fork because three.js dropped support for WebVR and Firefox desktop does not yet have support for WebXR.

Thanks Robert appreciate the response!
