I just finally got around to playing around with these, and it’s one of those systems where there’s a lot of potential, but it can be difficult to image what sort of useful things can be implemented via geometry nodes (so far.) I was hoping to get some other people’s ideas about where geometry nodes are exciting for them.
For me, it seems like the current implementation is heavily focused on point instances, which isn’t something I’m into, but there are a few new things that I think are potentially useful:
Non-destructive joining (not booleaning) of geometry. I think I might have a few operations that this will simplify.
The ability to create some frequently used weight paint operations as reusable node groups. Setting up the ability to drop weights, invert weights, steal weights are all useful, but require multiple modifiers that are painful to set up. A single node group should simplify these operations considerably.
But other than those two, I’m having trouble understanding what I might do with geo nodes. It seems very WIP (color ramps without VCol attributes?)
