Hello! I've been running into an issue with rivets along edges, and not sure how to solve it. I'd like to have them like in the image. Masking out the edges and using a tile sampler yields random results, tried vector maps and cant get that to work either. Starting to think maybe FX map or pixel processor but I have no idea how either of those work.. Any ideas? Thanks!

I wonder if something like this might get you close. It is far from perfect, but until we get a node that follows a path.
I used edge two edge detect nodes, the first to detect the joins and the second to add a path for the rivets. I then used a tile sampler at 64 x 64 to place a single point wherever that path crossed.
I next took the ouput of that tile sampler and used a vector warp to move it based on a bevel of the panel shapes. This moved the points off the strict grid and toward the edge o

This problem got on my mind and another method occured to me.
This alternative might help depending on the panel layout and rivet spacing required. Again it's not perfect, in this case it missed a very small panel, but for me it worked slightly better than the last method if fewer rivets with larger spacing is required.
It starts with creating a path for each set of rivets (make it is wide enought to capture positions at the next step).

I next took the ouput of that tile sampler and used a vector warp to move it based on a bevel of the panel shapes. This moved the points off the strict grid and toward the edge of the panels giving a better alignment with the curves and angles.I did it that way rather than using the vector displacement in the tile mapper as it gave a finer control.
Then a histogram scan and a shape stroke to enlarge the points and form a circle at each point.
Next a flood fill and flood fill mapper to place a rivet in each of those circles. Keeping that stage separate to the points and warping, kept the rivets circular.
It is far from perfect but hopefully may spark your thinking.

It starts with creating a path for each set of rivets (make it is wide enought to capture positions at the next step).
Next a flood fill creates a flood fill on each individual rivet path shape and a flood fill mapper is used with a tile sampler making circles (8 x8 and 0.5 offset). Then a distance note to expand the positions and histogram scan. Balance the distance node and histogram position to ensure individual rivet positions are large enough to hold a rivet but do not overlap.
Then a flood fill mapper to put a rivet in each position.
