How do I apply and output 3d texture for printing?

I’ve been looking about, but I remain unsure of what exactly takes place in terms of outputting a printable 3d textruer. Specifically, I want to apply a stone wall treatment to a fireplace to print out for an actual model.

This question was here two days ago…

Maybe build something with “PannelingTools”

Right. I’m going to look into 3dCoat
