By the way, I will go back to the **quadrangulate **discussion we had a while, my geometry comes triangulated as it comes from a game engine and doesn’t keep quads.
In the end, I replaced the dissolve node by a wrangle in the node and it runs way faster, I basically recreate polygons myself. I will put it there if someone needs it
It might not work with all cases, works in mine, though
