[Abilio5EC9]

hi

how can i use the curvature bake of this object:

in this object:

the difference is the broken piece that doesn't have to receive curvature:

I actually wanted to apply dirt to this piece
Except on the inner faces of the broken part, in the red circle.

Does anyone know of a tutorial?

Thanks

Are the unwrapped UV layouts exactly the same - except of course for the addition of the broken edges?
