Solar Analysis node issue

Not the answer to your question- but in my experience, I’ve tried with a number of Autodesk environmental analysis tools, but given up. They just seem to be a half-hearted attempt & I’ve never been able to get any decent results- but happy for someone to set me straight.

Ladybug/Honeybee in Grasshopper are pretty well know.

Less well known is VI Suite, which works within Blender. Whilst it is yet another application to come to grips with- I’ve found it fairly easy and the node editor in Blender has some similarities with Dynamo/Grasshopper.
