The VI-Suite Sunpath node creates a 3D sun path diagram, sun lamp and sun mesh within Blender. The node also enables real-time control of sun position and colour based on day-of-year and hour-of-day settings. These controls also modify the Hosek/Wilkie sky orientation for realistic sky control within Blender’s Cycles rendering engine. The short video below details the operation of the node.

Thanks for this amazing work. Is there a way to do North offset so that we don’t have to rotate the building? This feature is available in similar addons.
Thanks for this greatly useful work. Can we have a north offset setting so that we wont have to rotate the building? Then this addon can be integrated in the design workflow throughout.
Thanks for you comments.
The whole VI-Suite uses +Y as North so although I could put an offset on the sun path node this would break with that consistency. Creating an offset option for the whole VI-Suite would be a considerable amount of work as it would effect HDR sky mappings, wind rose projection, Radiance and EnergyPlus geometry co-ordinate export etc. In short it isn’t a priority for me at the moment, but it is something I will keep in mind for the future.
Thanks for your reply Ryan. I understand that it will take considerable effort and can’t be on priority. For anyone who might want to contribute I will make a case here for this feature.
In a small-time architectural practice in a developing country, the vi-suite can be a tool used throughout the design process. (Even where compliance is not asked for) Design requirements can change from the client side anytime. A minor change like say the size of a window can occur after the design is well developed. Then it is disconcerting to copy a detailed model to another layer and rotate it for analysis. The North-offset will make the capabilities of vi-suite readily available at all times.
I am hoping to be able to contribute sooner or later as I am trying to use this tool in my everyday practice.
