I think your spotlights look very nice. Kind of like IES lights. What kind of map did you use?

Your scene lack contrast a bit though.

here is the map... I think somebody can make far better !
In B image exterior image wasn't real black so we can see square corner..
Lake of contrast is due to the fact I rendered in HDR : my image is far more contrasted than HDR (but not enough).

Nice work. The spot light effects are rather good.

Where did you get the pool's tile texture?

I found this nice IES Viewer utility that reads IES files and renders simple representation of light. Maybe you can use it to make some nice maps?

I think you mistake me for somebody else :cry: (I'm not G.)
As I understand it, I should convert power graph is a spherical map.
I open IES files and it is not frightening but I'm very very (very) bad in math... If somebody here come from MIT ?

LOL!

You missed IES viewer render ability I guess! :D

There is a button that will render the light representation - search for it on the left pane...
