I had great hopes for geometry nodes. I imagined they might be perfect for modelling regular systems in which there is a strong underlying geometry, modified by secondary variations in scale, position, orientation - things like flowers, leaf patterns, scales, feathers etc. In the picture below, geometry node would be great for modelling the dust and dead flies but when it comes to the main elements (flowers and leaves) right now it looks like I will have to stick with particle systems (which are tricky).
If I am missing something about the capabilities of geometry nodes and someone can put me on the right track I would be grateful. Alternatively I can see I might have to wait and see how things evolve.
