Cryptomatte for Photoshop?

[carsonjones]

Wondering if there's any update re. the Cryptomatte plugin for Photoshop?

[atrask@hksinc.com]

Is there an update? This would be an extremely helpful tool.

Progress, yes - work is ongoing - nothing further to announce.

Hey Daniel,

Wanted to see if there was any further developments on this? Do you guys have a target release date?

Best,

Richard

Would you need to be comping in floating point / PS 32bit to make crypto-matte work properly? Would it work accurately once you've converted down to PS 16bit / 8bit?

It's done, it's here:

https://www.exr-io.com/exr-io-2-00/

Full Cryptomatte support, mipmaps, ripmaps, even correct reading of DeepPixel Data (we artists can't do anything with it, since Photoshop can not show it, but it is good for some scientific researches in the future, etc). Chromaticity, ColorProfiles, i think everything OpenEXR offers at the moment.
I have even loaded on my crappy workstation a 5 Gigabyte, 20 Vray Render-Passes Monster EXR-file artwork in 35 seconds. A very, very Great compliment to Vlado and CG-guys; Vray does such a great Cryptomatte sorting of objects, layers and nodes, it is so clean, so perfect - it is a dream to work with it!

It is free, use it.

Somewhere is tutorials section are even Vray Video-Tutorials about how to render Cryptomatte in Vray and design artwork with it in Photoshop.

Oh cool, thanks for sharing!

Holy sh*t balls. Trying this right nooooow! Thank you!

It works well, just cant work out how to get masks for objects behind refracted objects...

I just tried this and it doesn't work like you said. And I think I know why: this would be too difficult I think because, with refraction comes distortion: the actual object isn't always in the same 'place' when you see it through a refracted surface (unless you have a very low IOR, and even then with organic or non planar surfaces you still have distortion.)

Exr-IO reads also the Cryptomatte transparencies. In Arnold, you have the extra checkbox "Blend", the control if only the first surface writes to the AOV, or if the value from all transparent surfaces is blended together.
I could not find it in Vray, i am quite busy at the moment with other stuff. Please consult Vray Docs or contact Vlado for this feature.
thanks

WOW! Finally, someone did it! Thank you very much!

I'm just now testing the new EXR-IO. It's working as described and I'm using it with the vraycryptomatte element.

the workflow I am using is to render out the .exr file form vray frame buffer and then open the 32 bit file in photoshop. all the render elements are there as layers thanks to EXR-IO. after adjustments and etc I save as a smart object and convert to 16bit. Now I can use the rest of the vray adjustment layers lie curves and etc. If I need to go back I can open the smart object and all of the 32 bit layers, masks and etc are there as before.

What I can't seem to achieve is having an alpha channel of the render (rgba) available after the file has gone thru the smart object to 16 bit step. Once in 16 bit from there is no alpha available.

Can anyone suggest a good way to bring the alpha channel into the 16 bit space? I would use it to create a mask for adding a backplate/sky/etc behind a 3d scene with building and landscape elements.

I'm spinning around in circles trying to figure out how to accomplish this.

hello mark

before coming to the point of alpha channel, isn't it that Vray EXR workflow demands saving image directly through the renderer in saving FrameBuffer from the main-vray interface pannel? I don't have a proof but as far as i know saving image from FrameBuffer Window is not the way how to correctly save EXR data containers.I do not know anyone doing it this way, maybe Vlado can explain the difference (if there is one) between writing on disk during rendering and saving EXR from VFB.

Igor, how easy would it be to make this compatible with Affinity Photo?

Daniel wrote above that it is not possible at all, since AffinityPro does not have SDK for developers. His message is from 2017, it would be good to know if they offer one now (it seems you have good connections to Affinity developers, can you get some info please? thanks!!
