Hey all, so I took a stab at adding support for custom blocks to the Node Material Editor.
I based it on Custom Frames and tried to change as little as possible, so the new code and UI should hopefully fit in well.
And if there’s some things that need to be added or changed, I’m down to work out a second draft of the patch…
Let me know how it looks so far and if it seems like a good idea?
And here’s a patch (from the same build).
