A grid pattern using different fruit images in sequence, takes from a reference group with the individual fruit layers.
Example of using Group layers, Repeater indexes and Instance layers using the pick from group setting, to create an instance of a selected element from a linked group layer. A similar technique and result can also be achieved using the Replace group node to replace elements in an existing group using selected elements from another linked layer group.
There’s also a Youtube video with an introduction to how this type of mixed pattern can be made in Paragraphic: Mixed fruit instance pattern.
