Hi,
Thank you for reaching out.
We are sorry to hear about Lumion crashing when adding the Ray Tracing Effect.
We were able to reproduce the issue and it seems that the culprit is a corrupted Imported Model:
* Insert screenshot of said Imported Model
After deleting it we were able to successfully add the Ray Tracing Effect.
With that being said, please select the Imported Model, and click on Select all identical objects:
Then, delete all copies of the model.
After that, try re-importing the model (you might also try redownloading the Imported Model from its source) and if it doesn't work, unfortunately, you will have to replace it with another one.
We are sorry that we don't have better news regarding this.
We would appreciate it if you could provide us with the following information so we can try and pinpoint the cause of the corruption:
1. A Diagnostics Report, Error Log, and Importers Log.
- Knowledge Base: How do you provide a Diagnostics Report?
- Knowledge Base: How do you provide a Lumion Error and/or Importers Log file?
2. The Imported Model:
- Knowledge Base: How do you upload files to Lumion staff?
3. The origin of the Imported Model, and the method of import used (version of Livesync if that was the method used).
Thanks in advance.

You can add new (basic) Tables in the HubSpot Editor directly.
If the layout does not work, then you can copy/paste or recreate the old Table from ZD. Where possible the Table has also been copy/pasted from the source page (see link below in 3.). Instructions, see this article: Copying an old Zendesk Table over to HubSpot
