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/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.
