Model scale and unit

Hi,
I use Cindigo for light simulation in architecture.
I'm french and i use metric unit, and more specificly cm.
But when I render with Indigo, it seem to convert my cm in m :(
So, if i want a "real" effect, I need to scale my model with 0.01 factor to have measurement in meter (even unit in C4D is cm).

It is possible to do this factor during the export, looking at the unit used in C4D, or there is a solution to tell C4D that 1m=100cm (i dont find something to do that) ?

It's global scale and it's on Indigo Rendering Settings object. Just set it to 0.01

Ok, thanks Pixie !!

So this "Global Scale Multiplier" is the factor of the unit used in C4D and meter used in Indigo.

Yep it is, this specific issue will be in the manual once it is finished (fused and me are working hard on it)

Ok ;)
... so I will wait a little this manual, cause i have other questions about Light, Light Normalisation and Emiter Materials...

I'm also translating the .str files in french. But there are some features I dont understand... I wait for the manual to finish it...

Just ask the questions you've got here so we can see if it is planned to add them to the manual, and if not, add it

Well then, what light normalization actually does?

It "scales" the light to be always at the same brightness, dependent on lumen, candela, lux/m^2 or candela/m^2
This will be described further in the manual.
For example if you set it to 20 lumen it is always 20 lumen bright, no matter how big your emitter is (those 20 lumen are disturbed over the whole emiters suface then)... if you set it to 20 lumen/m^2 it scales with your emitter, meaning the bigger the emitter, the brighter the light.

So the Light Normalization refer to a Material, but a C4D material or an Indigo one ? I dont understand how it works :?

And, if I use an Emiter Material, I can use it in a Layer Light but not IES...
If I use Light Tag, I can use IES but not Layer Light...
Perhaps, if I use a Light Normalisation, I can use it on Emiter Material and can have IES and Layer Light ;)
I'm right ???


And about french translation, if the manual is not to long, I can translate it too when is done ;)

The light normalization tag needs to be applied to the same object the C4D (emitting) material is applied to.
You need to set the emitting material in the light normalization tag and can use an IES profile for it then.
Note that the light tag is deprecated and just still there for backwards compatibiliy, avoid to use it if possible!

Ok, I add "(obsolete)" to the light tag in my french translation.
