Octane for Blender // Cryptomattes, Render Passes and using EXRs in Photoshop

[@fahim618]

wow!!! this is amazing. multipass is really powerful. can you please show us something similar but with animation. like in after effects or something?

[@edmund0dao]

awesome! thanks for sharing this workflow!

[@AlexPearce3d]

Glad you liked it!

[@goilo888]

For anyone not using Photoshop, you'll be pleased to know that the painting programme Krita (open source) will open up an EXR file exported from Blender with no messing around using a third party programme first.

[@AlexPearce3d]

That's awesome! Thanks for sharing! I will try to look into this.

Very good tutorial, thank you!

[@mustafagolbasi4389]

Good one! Helped me alot

[@DC-pl9kg]

This is super cool, thanks for the tutorial! The Dropbox link appears to be down however, can you reupload please? Thanks!

[@AlexPearce3d]

You're welcome! I don't have access to that Dropbox or exr anymore, unfortunately :(

[@rorymayne2190]

Thank you. Awesome tutorial! Could you possible create a tutorial on compositing in Photoshop using a shadow catcher plane in Octane for Blender? I was also wondering, do you know of a Blender Octane renderfarm?

[@AlexPearce3d]

I will consider it, I've been super busy recently. I don't know any farms for octane for blender unfortunately.

[@arthurschurin]

omg, thanks

Hello, how do you render in Blender Octane and get the Octane Output instead of the Blender Output?

[@aliazhar1]

still searching for this answer, i will try to figure it out and send it to you.

[@robob3ar]

cool

[@AlexPearce3d]

Thanks!

Hi, this may seem like a silly question but I am working on a photoshoot with a real model and need to render some objects seperately...I've done it the regular way, by just rendering out as an alpha but then the background and environment reflections etc no longer effect my model. Would this same method apply or is there something I would need to do differently?

[@ChidarumaSportCards]

Would this be the same if you render animations ? Or do I need to use other passes ? Not much on the internet about that especially blender octane..

[@AlexPearce3d]

It probably depends on what you do and where you are brining your animation. If you can use exrs in your pipeline, then the render layers would be there to be used in AE, nuke, fusion or whatever (the workflow may be different though, I guess that's probably what you're asking about?)

[@ChidarumaSportCards]

@@AlexPearce3d hey yeah, was asking about the workflow, so I tested it out and it does generate a exe file for each png image, and then I can load exr sequence in after effects ( not sure if that’s the right way to do ). Or do you need to load in the png sequence and the exr sequence.

[@AlexPearce3d]

Great! No you should just need the exr files! You can use dwaa, that's a good compression to use. I haven't honestly tested that workflow, so I don't know exactly what you need to do to set it up properly.
