Converting mograph color shader to texture for obj

[Alex_Manic]

Hi everyone,
I fractured an object using Voronoi and applied a color shader to get random colors to fragments.
I'm wondering how I can apply or bake mograph color shader to each individual object.
I need to export obj with colors I've set up.
Hope I've explained it clearly enough.

Here is the main project and another one where I've connected the fractured objects.

Appreciate the help.
Thanks

Hi Alex_Manic,

Than k you very much for the file and for using Dropbox.

This is a little bit tricky.

Your linear cutting of the object allows for a straightforward workflow.
First I set the gaps to something smaller (5cm instead of 10cm)

Then I took the orientation of the related Matrix for a Standard Render Camera, so it faces the "cuts" perpendicular or, in other words, as straight stripes. This means the camera needs to be far away and has a long focal length. I rendered this out an Emmision only.
I then used the standard camera with a standard material (meaning I was not in Redshift then) to set up a simple Camera Map.

This allows me to project the image back to the object in any resolution.

I reset the gap back to 10 cm, and in a Color Vertex Tag, I used the Color shader to use the Camera Map Material tag. This sets all points (Vertext) to the needed color.

Back to Redshift, a material with a simple Vertex node, works now.

My tip is to store it as Alembic.
