So this is basically a dividing wall in an unnamed country. I’m trying to weather the tops of the concrete slabs. I’m using the procedural leak/spill here. I’m trying to make the leak/spill i.e. the white paint-like weathering START at the top of each slab instead of being plastered across the whole row of slabs like they’re a contiguous wall. Not sure how to do this. Snapping, perhaps? Really too new to blender to know. Help?
