This is a very demanded feature, that was removed for controversial reasons during the port of the field prototype to the actual final implementation, please check this topic Named Attribute Nodes in Blender 3.0
after using Geometry Node of 3.0 extensively, I can’t agree more with my past statement about the removal. The new named attributes access is just so awkward to work with, it is also very inconvenient for studios trying to establish their own pipeline
Can the Object Info node act as both of your object & collection nodes? It is necessary to have both of these nodes you made? Image input node seems good to me though.
No they are two separate node,
i am still working on the patch, it seems to work except very specific issues, i will have time later this month to sumbit the patch
