Hi @charliebrooker,
There was a bug in the 1.6.1 version of the component when using the view factor method. If you update with LB Versioner you should get the 1.6.2 version (which works for your sample).
Here is the model from the video in case you still need it:
- base_model_for_gh.3dm (1.8 MB)
- option_one.gh (92.4 KB)
