I am wondering if there is an easy nondestructive way to determine which faces of an object get one material vs. another.
For example, if I have a low poly mountain created by adding the "landscape" add-on and then I want to apply a "snow" material to the upper faces without manually assigning them by selection, can I use a hidden cube to overlap the ones I want the "snow" material for and then have that determine the assignment?
Can this be done in geometry nodes or material nodes somehow?
I always prefer nondestructive editing as it provides much faster prototyping and experimentation.
Thanks for any ideas.
