I haven't upgraded yet (still digging thru the couches for spare change).
Anybody used the new IES features in v2 and care to talk about it? Do you like it? Render times? Does it work with multilight? etc.

Yes, it's a time saver. Works with multilight.

How are you applying it to geometry? I found in the manual that the best way is to create small spheres? is this what your doing? How do you control the direction the ies is pointing etc. Overall though it seems to be pretty great!

i just created an ies light in cinema4d.

my other .ies files didn't work, but the ones supplied with maxwell v2 did.

i didn't read your post but i created tiny spheres as well lol
first i couldn't rotate the direction, but you need to rotate csys instead of geometry.
then it works, havent tried multi light yet

Yes, apply it to a small sphere. I believe there is a direction marker that shows up in Studio to show you the direction. Haven't tried it in Max yet to check if there is any special display.

I thought the IES features uses the Y axis - pointing up so that emission can then point downward.

I found this archive full of IES files, they might come in handy..

Btw, i wonder what type of studiolights are available as IES so i could make good use of IES for my photostudio setup thingy's,
and now in combination with ThinSSS there is a chance it would kick butt!

IES lights I think are not suited at all for creating studio lighting, you either have a softbox, or a smaller strong lightsource which you can create just fine with an emitter plane. It would make no sense to create an IES profile for a flat plane softbox light.

Hm yes that could ofcourse be true, i thought about that too. I think it has to be tested first to be verified if IES is worth it or not. They might not contribute with anything except a possible longer rendertime.
Thanks for your tips Mihai.

Its best likely to have a few IES that vary for effect than to have endless collections at the moment because they are so specific to lighting hardware and manufacturer's specifications.

Hi to all,
I tried the IES emitters and it's a great news for Maxwell.
It's really time saver and you can get easier good results than with MW 1.7 ...
..but now I'd like to introduce a new question. How can we model the light fixtures using the ies emitters at the same time?
I mean, the IES profile takes into account the geometry of the light fixtures...so if you don't need to see the light fixture in the scene there's no problem. model a small sphere (how small? 1cm, 1mm diameter?) ... but if you need to see the light fixtures in the scene? how do you model it? How can we obtain the result of the lens litten from the lamp without seeing only the small sphere litten from the iES emitter material?
Hope the question is clear.
Regards
