One thought to that is GN creators can tick some options in their node tree (whether by cache nodes or something) to show cache buttons in the GN panel.
Here’s a panel from some random product I found
If they want, they can add some buttons where it’s applicable
A little addition to the cache design discussion.
If we stick to the idea that a cache always exists for all real data sockets, then that cache should be available to render previews under all nodes (like the preview in shader nodes)
This is so, in my opinion, that if we already have this data, then why not provide it for reading to all those who may also need it, as an example, to the previewer
Honestly, in general, we are missing a lot of visual indicators for states of things.
One being the result of an operation (preview above nodes) and second one would be visual guides for simulations and such.
At least these 2 i can recall from the top of my head, i’m certain there’s more.
Is an add-on for the preview ?
