I meant in terms of setting up the lighting itself -- the setup and modification of these HDR Light Studio IBL is lightning fast, almost anything can be done and changed instantly... huge amount of flexibility and speed which I can't see as even remotely comparable to the time it would take to setup "physical" lighting, even in the form of simple planes.
If I was doing commercial product, car, or advertising renders then this workflow is a "no-brainer" as It would likely take me many hours to set up and tweak "physical" lighting which I can set up with this plugin in Studio in just a few minutes.
Particularly of interest to me here is the ability to work with these lights over any HDR or EXR background... the combination really makes setting up complex lighting super quick.
I want to get this, but I'll have to wait until later in the year... I don't have the money right now
Best,
Jason.
