Thank you Julius,

I would love for you to cover that portion in your blog, this is such a great workflow method. I’m looking forward to more look dev topics being covered, especially your Katana workflows!

Hi Darcel!
In short: spherical transforms.
You can convert your HDR from latlong to cubic (choose a square format) and rotate it into place. Then do your clean up work and after that convert it back from cubic to latlong and merge it over your existing HDR.
I might as well do another blog post how to do it in detail.
If you have any further questions please let me know! :)

cheers,
Julius

Thank you for this very useful gizmo! I have a question, how do you adjust your lights that are skewed and need to be formatted to fit your area lights? Do you adjust your arealights scale to match your bounding boxes? This example is kind of made for this scenario however there are many lights that are distorted and need to be flattened for your arealights. Im curious as to how your workflow solves this. Again great script and time saver. Cheers!
