I found a more optimized solution to align instances by normals when those instances are placed on vertexes. It uses a lot less nodes as there is no need to transfer attributes between the original mesh and points.
This video updates the previous one regarding the alignment of instances on vertexes but can not be used for normal alignment of instances on edges and faces. For that solution please watch the original video:

I hope this update is helpful.
Thank you for watching!
