Built-in IES editor

[jodestroy]

I think it would be a very nice improvement. Something like the IES generator by Karba in the vray ies options. should not be too hard.

what do you think?

[vlado]

Hm yes, but I thought the whole point is to get the data from actual factory products?

yeah but often I got the editor for the fine tuning to get another effect. Or sometimes when I don't know what product use but I have a light shape in my head I can make it from scratch.

Could be a load button and an edit button.

If you really need to create handmade IES patterns, there are many free and simple IES generators out there. For example this one.

I don't really see the point in doing so, but hey, it's your digital world.

I already have it. Just thinked it would be simplier to have it directly in max. For the moment, when you edit the ies, you need to reload it in the light and re-enter the intensity setting.

Am I the only one who use a IES editor? IT's pretty useful. We make a lot of custom design, pretty limited models or simply the IES is not supplied by the compagny.

[Aldaryn]

For example, I'm pretty against visible contrast in a light source's distribution. Manufacturers actually struggle to get rid of uneven distribution, and to produce a homogeneous output. We've got a set of "fancy" looking IES-es to drop in if we need the drama, but I seldom recall using custom made IES-es to match a particular design. If you need precise control, there's numeric input, and to roughly sketch up a pattern, there are the editors. I'm not against a feature like this, but since you asked the Am I the only one questin, this was my 2 cents on this topic.

What I´m desperately missing is the correct preview of VRayIES lights in the viewport by using the ShaderM 3.0 option. That prevents me from using them and getting a possible gain in render speed.
Any chance seeing that in SP3, Vlado ?

While an integrated IES editor in Max might be nice tool, it really seems to me to be outside the scope of VRay. There's nothing in an IES editor that should be specific to the VRay rendering engine.

No, this is not planned for now... you'll have to use the 3ds Max photometric lights for this. Probably a better approach would be to be able to flag those lights so that V-Ray can replace them with V-Ray ones when rendering. But in general, I avoid having anything to do with 3ds Max's viewports; the potential for breaking something is too great.

Talking about IES lights and generators/editors.

Have any of you guys found a generator/editor like the ones posted (Free stuff),
BUT ( BUT ) an editor which works NON-Symetrically. I have 2 editors, but they both do
a symetry looking IES file, which is kind of 50% useful.

ANYONE ?

I think that's part of the specification of IES isn't it? So a non-symetrical light couldn't be defined by IES.

[Dschaga]

I also don't think it's a good idea to "paint" IES lights:

If you use a selfdesigned IES characteristic, you are far away from real life conditions! Not, that it's unusal in CG to render unrealistic scenes ..but the reason why i always prefer IES from real Products is the fact, that you also get the right cd/m2 values and this is something you will sooner or later like, because if your scene is dark, you **have to** place additonal or brighter lights to get the mood you want.

..and at least when your client want to order "your" IES light it will be a painfull experience for you!

[Aldaryn]

(...) because if your scene is dark, you **have to** place additonal or brighter lights to get the mood you want. (...)

Reality? Oh, come on! Have you ever been to interiordesignerland? or architectland? Light comes from nowhere, and illuminates eeeeverything!

Seriously, the extents designers go to bend reality on viz just because they can is frightening. And when the structure is finally built, the lights are turned on, you can see many, many surprised faces. Reality is unforgiving.
