Blender with cryptomatte rendering for Photoshop


lvalics writes:

I have followed 2 tutorials that raised my interest and I created this tutorial where I show how to export from Blender for Photoshop and keep all the objects as a separate layer, use in Photoshop to create masks.

It was inspired by  How to Render Cryptomatte in Unreal (NEW in 4.26) and Exr-IO Blender Photoshop Compositing Tutorial.

In the first one, I saw that William Faucher has succeeded in exporting from Unreal Engine to Photoshop by keeping the mask for each object as a separate layer. As seen in the video, it is very helpful to have these masks when doing compositions in Photoshop. You can just select an object, then create a mask and play with that part of the image.
In the second video, I saw how that was done in the past.

But then I saw this nice free addon created by Sebastian Fischer.

With the addon, it was very easy to create in the compositor and export from Blender into EXR without having extensive knowledge on the compositor. So my goal was to get all objects as a layer from Blender, then when I would click on it I can easily create the alpha mask to play with whatever I want from the image.

Of course, in the video, there are some extra layers exported. You can also experiment with those if you don't want to use the BEAUTY image (final composite). For that, the second YouTube link will offer some tips and tricks.

Any feedback is welcome.

It seems that at the moment I created this video, if I export crypto layers (objects) and import these into Photoshop, the group for the crypto layers will not be created, but the trick works for the other groups. Maybe this is a Photoshop plugin issue which I will report to the devs.

Hi! In my free time, I like to take photos and work in Photoshop on compositions. Since 2020 I dived into the 3D Blender world and I am happy that I can create various environments such as medieval, futuristic etc. I like to create places that cannot be reached to take photos. So I create my art in 3D, then I shoot pictures in the studio and finally I do the compositions in Photoshop.
