Hi, I am back.
Hope it's not that cold over there these days.

I tried your instruction by copying and pasting the same nodes to my hip file.
I still can not achieve the same bright obj with the geo light.
I wonder why ?
I wish i can make my human body obj with the geo light like the bright sphere obj in your file.
Can you help me further?
thank you very much.

Steve
