I fully agree Tim. The lights
in this version are extremely nice. I was playing with the demo last night and
the presets are great. In no time, I got this simple test scene I use lit and
rendered beautifully.
It would be great if *cough* SI *cough* would
take a look at these lights.

Here´s a link to one of the autodesk sample movies for

showing viewport display for IES profiles and revamped
lighting:

The
IES stuff is beautiful. Lights that look convincing, no way...
One
could argue about the daylight/timelapse implementation,
especially since
the basic functionality had already been
there (they implemented time of
day, location and so on years ago)
But still, the IES stuff is
great.
Personally, I would like to have a functionality similar to
the
editing of Photoshop "Curves", where you can interactively model the
distribution of light (or an existing IES profile) to fit your needs
but
the above is still better than anything else currently available
by default
in any of the major 3D apps.
As I understand it, an IES profile maps
intensities and distribution
across a hemisphere,where you look down
straight from above onto the flattened and "relaxed" spherical coordinates,
creating a look-up
table for every facing angle (>normalangle) of light
receiving geometry.
Which sounds alot like "realtime ZBrush MatCap" and
"BRDF" Materials.
Therefore, looking into finding synergy effects in
existing shader
model research as well as lighting models might finally
allow
to achieve more appealing results in a user friendly way,
where
realism is the basis editable as desired.
In real time. In the
viewport.
Cheers
