I had a feeling this node existed.
I can’t guarantee that it’ll fix the particle bleeding between separate spheres, but I have a strong suspicion it’ll help.
I copied over some of the improvements I made in the MetaballsToSDF script into my Energy Ball V3 project and cleaned up the VFX graph as well. I didn’t test anything—it’s Art Basel week and ya boy is a bit fried in the dome. I still need to add or adjust the code for the particle field transform, since the player sphere positions will have to be moved in order to work inside the metaball grid.
