Help with designing a LEGO Geo nodes setup

HI! I am trying to design a LEGO geo nodes setup based off this guy: Quixel to Lego Converter
But I am running into an problem: intersecting instances!
The mesh is being converted to a volume, and then points are scattered in that volume. Instances (lego bricks) are scattered on those points.
But some lego bricks are appearing on others (conflicting instances).
How can I solve this, or better yet, how did this guy:Quixel to Lego Converter do it?

If you want I can share my node setup/blend file.

Watch this…

I did actually! :sweat_smile: I’m trying to build off of this to add other types of bricks on top of current 1x2 bricks.

Did you watch this one also?

Not yet. I will. Thanks!
