Import an HDR sky map

Hello everyone,

Is there any way to import an HDR sky map into HB/HB+ for daylight analysis? I have an HDR map of sky and trying to define a custom sky or sky vectors based on the luminance pattern of that.

Thank you!

As far as I know, translating a .sky file to an HDR image is really straightforward but I don’t think you can easily do reverse translation.

@mostapha might know more .

Hi @Mohammad,

You should refer to the related discussions on the Radiance forum. Depending on what type of sky you have and specially if you have sun in the scene you might need to make adjustments to be able to use it for a Radiance sky. Once you have that then you can use the new sky in the scene instead of the ones available in Honeybee.

See this discussion for example:
