After testing this Is the best result but there is a problem.
This system use diffuse for create a cryptomatte and of you have similar diffuse colours isnt good.

I'm not sure if this is what you are asking, but not all channels work as stable Cryptomatte output. This video isn't specifically for Lightwave, but discusses which matte options work reliably.

Hello,
i was checking that video as well.
Anyway, it looks like in C4D you have many options for grouping Masks, i.e. assigning object tags. So in case you need that some items are into same single mask, you can do it.
I investigate this a lot, but it looks like there is not a way to do same in Octane for LW.

Can you confirm ?

Thanks
Paolo
