Good idea. Sign me up!

What do you say Stefan :p?

In that case I think we should all try to move the release date to december!

(I like BD-presents too :D)

Is anyone able to give me some ideas on using IES lights and how one sets them up in C4D. I just watched the movie that Renato linked to and it’s very impressive. I understand the idea behind it and also see now why having scenes that are based around cm grids is important. Do you have to model the light and use that object as a light or can you use normal C4D lights converted to Vray IES lights. I can see a tidy little model library of real world lights being made if that is the case. I found a tutorial and it shows modelled halogen lights. If my thinking is right you have to model your scene in realworld dimensions to get accurate lighting effects. Also you have to measure how far lights are from surfaces to get the correct look.

I’d just be interesed in the workflow as it’s all a bit new to me

It’s as easy as setting the light color.

IEs lights are simple but but to choose and find the right one can be very tricky.

Ies light simply represent the area how light gets spread from a light source. I would see its a lightobject area. companys make them and they are based on a real world scale.
But there are so many ies files from different lamps. Of course you can choose the right one from your lamp manufacturer but renato made it even easier for us.
In Vrayforc4d
you need a light object and simply add the Vray light tag then it is possible to enable Ies Lights. What you now need is one or more of these files , Simply set he path to it and you will see the preview of it. There you can ajust the distance from the wall and multiplier factor. Those values make it easier to understand and select the right one ies file. Usualy you should not be able to ajust them because they represent a certain light spread from a speciefied light source.
Through this preview you can see what happens if you place the light in fron of a wall ore above a floor. If you are not satisfied with the ies ‘light spread’ you need to find adifferent one. The next button lets you load the next Ies in the directory and make life more easier. within some time you will have a favorite ies libary and the preview is the tool to see how they look like. the good point is that saving a Project also copies the Ies files used in the project.
of course you have to place the c4d light object in front of a wall or other surface to see the result of tose lightspred information. Its like a 3D light gobo

hope that helped for brought some light to the usage of ies lights

cheers belushy.

I assume that we will be getting some IES light presets as part of Vray for C4D. Or will it work with existing ies files. What format would they be in?

hi Richard,
in vrayforc4d you can use all producer .ies profile.

A friend of mine that happens to do use 3D Max was very surpised about IES preview in Vray4C4D, and told me that in order to get that preview in 3D Max you have to use separate plug in. We get that with the whole package!

Thanks Vray4C4D team! :slight_smile:

A little video with the Ies preview.

Edit: i’ll make better front preview… :slight_smile:

#1932

It’s nice! Cool thing!!! :thumbsup:

i’ll make better front preview…

Maybe needs to add ies-creating :lightbulb tool-dialog :rolleyes:
or … ohh futureeee! :banghead:

#1933

Hello IlaySHP,

there are some Ies Creator free around :slight_smile:

Cheers

In general, I understand using ies data will give us more realistic looking lighting. Do we pick a lamp, say an A19 60w or a halogen MR16 20w with a 10deg or 36deg spread, and the ies is automatically plugged in? I do not recognize the ies data included in Renato’s vid:

#1935

you d/l the ies data for a specific lamp from the web

#1936

In all the rendering engines I had in my fingers real world scale has to be applied when IES lights (besides other effects) are being utilized. If you look for IES editors you can find programs for the definition of IES lights. There are also quite a few ready to use librarys out there from companies who produce light fixtures. It’s not only halogen lights. All sorts of lights are defined with their custom fall off and other IES definable characteristics. Using a nice halogen light definition (IES) sets intensity, color, fall off and gradients (like masks) automatically. Slap a row of halogen IES lights close to a wall and you have an instant cool effect. And so on… Street lights and all sorts of metal vapor lamps (e.g. sodium) have been spotted.
Cheers

I found some good resources for IES lighting. I guess since we’re discussing it it can’t hurt to have it in this thread.

did i read this correctly, that all scenes need to be in cm for IES to work properly? all my scenes are in inches.

#1939

The way IES light data is calculated relates to real world dimensions. So when making a room for example instead of making it 2ft wide by 3ft, you’d make it 20ft by 30ft. Whenever I make stuff I pay no interest to measurement whatsoever. That of course will have to change once I start using IES lights. If you use IES light data it will only be of use if the environment it is used in is to real world scale.

Please correct me if this is wrong but this is how I understand IES data to work. I also figure that you could change measurement from cm’s to inches or do a simple conversion.

Richard

#1940

well, that’s hopefully what i wanted to hear. i have all my files the correct real world dims, i just am wondering if the cm settings for the IES will convert the units inside of vray, or if i need to convert those numbers somehow.

thanks
