Noseman, your UI idea takes up way to much space.
It's not effective from that point of view. Better to have some other type of
selection thingy for the lights and with proper names of them which i hope
will be stored in the MXS file

Way too much space? C'mon, it's much more effective than selecting
each light one by one instead of having them on a single panel.

If you have actually hundreds of single lights then I doubt that M~R is
able to work with the sheer data volume, and it doesn't make too much
sense either.

I guess we agree on proper names for the lighting channels, however,
IMO they should also be saved in the MXI, not only the MXS!

Cool
When can we play with it?

I won't give it to the ones who are asking hysterically
(joking*)

then give it to the others (joking too)

[thomas lacroix]

great news, it s a step further of what we can do with multiple pass rendering in cinema4d where we already can manage to change the lights diffuse, shadows individually in post.

Now I had this idea this morning... suppose you make an emitter plane out of several smaller planes, when they're all turned on you have a big plane, when only the center one is on you have a small emitter... with this new feature you could build your lights like this and not only change light intensity but also emitter size
This way you can change location of your key lights, flood lights, fill lights etc by changing how much of the emitter you want turned on and how strong...
Good idea?

to ludi: exactly that, look ah this topic:

Someone mentioned changing the color of the lights the same way you can change the intensity of the lights in that video. I don't think that's possible without a recalculation as a lightcolor change would affect so much in the rendering, however as usual i could be completly wrong about that i hope i am wrong.. hehe

thx maurizio,

Seem's there are still some mystery about the emitters...

[dutch_designer]

Exellent idea dutch_designer!!! Very ingenius!! =)

I supose with your idea you could also place light pannels next to each other in a circle around the subject and completley control the angle and intensity of the key, fill and back lights. It would be amazing to build a lighting rig like this! Sort of reminds me of the rigs that Paul Debevic builds to relight subjects.

Heh indeed, makes playing with a studio setup so much more flexible

Something else, if changing these parameters on the fly is so easy, wouldn't it be a breeze to make animations quickly with this stuff? Granted, it wouldn't be possible to make a sunset like this, unless you use lots and lots of emitters on the sun orbit to turn on/off... but still, would be very easy right?

I thought of another use for the new lighting feature:

You know how you can get unatural color shifting in highlight areas on a surface lit too bright, or when the sky is over exposed it turns a yucky cyan color instead of a pale blue? This problem is caused when a high intensity pixel color is cliped disproportionalty into RGB values resulting in color shifts instead of the highlight being naturaly desaturated. Mental Ray has a feature to compensate for this clipping issue, called desaturate highlights. Maxwell should take this into account when converting and exporting an RGB image from an MXI file. Here is an example of what I mean:

http://www.maxwellrender.com/forum/view ... hp?t=12233

If you study the second image down of the converence room, you will notice the red and yellow shifting of the wall color which is supposed to be brown.

For now, there is a simple workaround with this new lighting feature. You simply export two RGB images to Photoshop with two different lighting exposures for the offending source. One with the correct illumination you want and the second one adjusted down in intensity until the colors stop shifting. Then in photoshop you place the non shifted exposure on top of the one with color issues and then turn on the Color apply mode for that layer. Presto, all the color artifacts will disapear and the highlights will be properly desaturated!!

Try, but you will keep the light that bounced off that surface, for example, the red glow on the ceiling coming from the wall.. that would mean you have to replace the ceiling as well, while the ceiling could be lit properly in the original image and be too dark in the second.. it would get really messy really quick imho..

having got to the end of the thread i thought i should ask a question.. (apologies if i missed the answer)

if you tweak all your lighting settings while a frame of an animation is rendering, will all the subsequent frames adopt the new lighting setting?

thanks,

mark

yes

[acquiesse]

thanks... i'd just to say...

i can see how for studio setups this will be a nice feature, but for arch vis, this will be revolutionary....

a sun study will require a single render instead of 12...
a day/night study in a single render...

wow

:)

Hmm, the sun moves during the day so I doubt you will be able to use this feature for sun studies
