How can I make a “Chibaku Tensei” in Blender?
I think you might have to link to a vid of the exact effect you’re after.
If my memory is good, I think a Chibaku Tensei is dark energy of some sort. Often portrayed in animations like Naruto, Dragonballs, etc… as a black hole of energy with white fire aura of some sort.
I think you could achieve that in Cycles with simple render layers and some particles/smoke effects and composite it all together.
In Eevee that would require maybe some fairly complex procedural material, but It can be done…
