Not much today besides some research. I didn’t find what I was looking for in terms of a solution to my problem, but I guess I at least know now what isn’t part of the solution. One advantage to having separate mesh instances for each grid dot is that you can detect when they’re clicked on (for editing). The multimesh instance doesn’t have that, not even (as far as I can see) for the thing as a whole. So I’ll need some sort of solution.

Day 16: not so sweet.
