I am trying to use the SV3D nodes. The workflow works in principle, but at the end of the generation I get the following error:

```

Since the VideoTriangleCFGGuidance is important to using SV3D, I'm wondering, what is happening here. Do I have to download an additional model?

I have attached the workflow.
