Firstly, the purpose of "texture" is to more accurately control the change of material ID.
For example, there are five color changing materials in this forest, and the material change is transitional, not sudden. I think at this time, if you can draw the map manually or use procedural map to assign material ID, you can solve the problem of transition.
In fact, I don't know much about the specific difference between "from uvws" and "from surface". But my original idea was to "get from the surface".
Of course, if you have a better way, naturally follow your ideas
Finally, if you can use "texture" to control the material ID, the "mat ID" in the "face fracture" operator can better control how the object should be broken. I think it's also a good idea. What do you think?
