Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Note: We still need some artist feedback to see if the node would be useful enough.
The node copies part of a geometry a dynamic number of times. Different parts of the geometry can be copied different amounts of time.
Besides the sockets shown in the mockup, the node also has a mode/domain (all domains except Face Corner) dropdown.
The basic behavior is:
amount
for an element is 0, it is not included in the output.0
andamount - 1
on the selected domain.Modes:
3D Point Grid Example (also also possible to create a 3D grid when starting with a single point when the node is used 3 times):

Is it possible to have the whole offset in the node? Would be very useful like the array modifier.
I think the offset should be applied afterwards. This way it's more clear how the Copy Index would be accessed. One can build an array modifier with this node as a node group.

Now I understand that this is the right thing. Now I use instances for duplication. However, due to their specifics, they are clearly spending more time than that.
If it will work faster than Instances on large quantities, then it will be preferable.
Automatic transfer of attributes is also a plus.
It's finally a win

Can the copy index drive Seed value of a noise texture, which will be applied to the duplicated object? So that each duplicated object has a new variation.
This is the main idea

Would it be possible for this to work with the new Named Attributes (custom attributes), so that they are copied over to the new duplicated data? This would open a lot of possibilities
