I think the porg shot is fine, personally.
You wouldn’t get that rear, pure white lighting effect around them from moonlight. It would be a lot softer. Just my thoughts though.
EDIT: Here’s a good fire reference. Maybe try a colour change from White to Orange just for that clip?
JEDIT: Just realised the lighter sky in Luke’s close up is from his glow. Did you use a fathered mask or a glow effect for that?
Wondering if this will help https://youtu.be/CKyztMknex0
Can’t pull the wool over your eyes, eh, MR? You’re right - I was trying to do it with a feathered mask. I’ll take a look at that video later; thanks for the reference!
