Hi Octane pros ...

I've been asking myself a philosophical question about the index channel ...

Is there a way to drive it with a jpeg or other image like we do with specular or roughness ?
If not, is there a specific reason about that ?
And if not is there a chance it may be implemented in the near future ?

Seems these question are of no interest for no one ?

Hi rmara,
the index value has been just enhanced in v3.08 for the new Metal material shader:

Currently is still not possible to use an image to drive the Index channel.

Thanks for the info beppe ! I'll have a look at it ...
Hope this may be implemented in the near future ...
