I realize this is a bit vague, but I recently started using the ies lighting add on, and boy are the lights nice. But like all my experiences with cycles lamps there is a perfection and fakeness to them, that I don’t see with mesh lights. I’ve checked MIS, and played with every parameter I could find.
Here’s an example with a worm I am modeling and texturing. It’s hard to find word but the mesh lights look more real to me, although the IES lights look better. Currently I am using both, as well as hdri. Any idea how to lower the uncanny factor from ies lamps?
