IF I NEED A DIFFERENT COLOR, WHAT I HAVE TO DO TO CHANGE IT ?

Hi Klein,
The colour comes from absorption in the medium.
Open the material in Indigo, then click on the little arrow besides the 'Medium' field. This will display controls for the medium. Then click on the absorption colour to change it.

Thanks Ono and another question, if i like to use this material for example, but in c4d can i do it without indigo?

Hi Klein,
if you are using the Indigo for Cinema 4D plugin you can import the material via
Plugins > Indigo for Cinema 4D > Import igm/pigm
The material will only render correctly using Indigo Renderer
