No. It's only good for specifying which objects interact with which
light sources. If you would, could you go into some detail as to
how the interface for MAX's feature works? Do you have some sort of
patch bay where you say "this light illuminates this object fully,
this light illuminates this object only specularly" etcetera, or is
it more like "This light illuminates only diffusely, and it illuminates
these objects."
It would be relatively easy, I should think, to make a light illuminate
only diffusely or only specularly (with a patch to POV, of course, not
with any current version of POV.) Given that, one could easily put
a diffuse-only light and a specular-only light at the same location and
use light groups to specify which objects each illuminates.
By the way, you could probably also use the superpatch to write a macro
that - given the camera parameters, image size, pixel position, and object
identifier for a specular highlight - could compute a light source that
would create that highlight.

I meant to tell you that the SuperPatch could do it, but I wanted to be sure
of what you meant. The only thing is that it affects everything, so there
is no specific control over diffuse and specular. I guess nobody has felt a
need for that until now, or I'm sure it would already be in the SuperPatch.

You know, with all the benefits that MAX gives you, you leave me wondering
why in the world you still hang on to POV-Ray. <dr. evil> I mean, throw me a
bone here. </dr. evil> Could you tell me why?

I agree with most of what you're saying, but in my view, I am more satisfied
with am image created "by hand." I have no ambitions of making it into the
movie industry, and quite frankly, most of what I see amateurs make in 3ds
is quite boring. Everyone wants to put as much in the image as they can. As
I see it, your imagination gets crippled. Lens-flares, all those standard
effects; everyone can do it. But create an interesting image in POV-ray; an
original one, with you own inventions. Ahh, that feeling I wouldn't trade
for all the gold in the world!
Power means not as much as your creative side. You might argue that more
power might boost your imagination, but that is not entirely true. Do you
think Beethoven's or Bach's music would be so great if they had
synthesizers? Or would the paintings of Van Gogh be as great if he had the
power of photoshop or the likes? Most masterworks are created with marginal
resources. Computer games were best in the eighties, I say.
Simen.

Well, I don't.
I don't have POV-Ray installed right now and I haven't for about a year
(except a month in the middle some time where I re-renderer some images I'd
made in it). I exist in these newsgroups to try to help people a bit, but
as you can probably see by now I'm by no means up with things like media (I
left in the halo days :)
POV-Ray still is an excellent renderer though and that's what got me started
on all this, so I feel I might as well stay around and see how it develops.

OK, the way it works is that each light you place in the scene has its own
options and switches like "Affects diffuse" and "Affect specular" and these
can be switched on and off. Each light also has a section in it which
allows you to move objects from the "affected" zone to the "non-affected"
zone so that the light only affects certain objects. Or, to put it another
way, if you wanted a light to affect all objects except for one, you place
that object in the second pane and switch on the "exclude" option.
Also, you can make any light only affect certain objects by illumination, or
by casting shadows, or by both.
It wouldn't be too hard to impliment into the Superpatch I'd think... the
diffuse/specular might be a bit more difficult but it would only mean
excluding a certain surface(?) or texturing calculation.
I might put up a page soon that shows some of the MAX features like the
lighting to give you a better (and at least more visual) understanding of
the way you can assign the lights to objects etc.

Can you site any real world situation where an object in the physical path
of a light source does not produce a shadow no matter how insignifigant ?
Why would you need such a feature anyway ?

You are one of those, what do you call it, ah yes, your an interloper.

It's purely for fine tuning Ken. Remember this is art, it doesn't have to
keep to the real world rules.
You might for example use it to highlight a certain object but you don't
want that object to cast a nasty shadow or some other group of objects in
the background. It does happen, trust me :)
I've used this feature a few times now and it saves having to reposition the
light and then set up another one to light just another object.
