I want to make a building construction effects like this: https://youtu.be/Ln2ZmgAaN1Y

I have tried it with geometry nodes but the results are unsatisfying and doesn't look as good as the reference. Here is what i have done: https://youtu.be/i-tw-7n_XC8

my nodes are mostly transfering indexes from one geometry to another by using the sample nearest node and then set position.

and my most successful one are using cube as particles that all appear on frame 1, and "destroy" them using a forcefield, then reversing the video later. Link: https://youtu.be/llGFrMYqbAg

i would like to explore my idea using the particles, but now i have a new problem. i cant make the particles to face the normal direction, causing the building to look blocky and unnatural

how do i "spawn" the particles facing the normal directions and also spawns it neatly, not randomly. i tried messing with these, but i see no difference

if you guys have any other solution i would like to hear them too ! thankyou
