CRYPTOMATTE

Anybody else feel octanes current matte system is in desperate need of a rehaul to be more production friendly. Since octane supports deep, something like this would be fantastic .https://www.youtube.com/watch?v=W_ltvSMrwnQ

Is there any news on when (or if) Cryptomatte will be implemented in octane?

I went to Arnold 5 presentation they have support with Cryptomatte now, aswell V-ray I think start become really standard on the industry
would be good to have something similar at Octane aswell.

They have a whole bunch of information about the object/material IDs contributing to a pixel, but no way to figure out the RGBA value of that contribution. If you for example would like to change the colour of the pink flower to blue in the small cutout of figure 5 you still can't, because the compositing tool still only knows that say 30% of the pixel colour is contributed by the flour and 70% by the bunny in the background, but has no information about the colours of the flower and the bunny.

-> Did anyone try out the system? Does it actually help in post beside making the organization of matte IDs more convenient?

Yes it helps! It helps very very much.
Yes we need it!

Is it hard to implement this?
Why no one of devs answers to this thread?

No time to get it in 3.08, but thanks to user unit we've put it on the roadmap. We'll also be adding a better system in the forums to for the community to help us better prioritize feature like this release to release.
