I’m not sure if this is the right place to ask about this as it’s very specific, but I’m not sure where else should I ask. The blender(help) subreddits aren’t very helpful to be honest.
You can see below what I intend to recreate using eevee (not cycles, very important). Now, it doesn’t look that bad, but it’s kinda dry, and I was hoping to give the core a bit more “umpf” by adding those little energy emissions coming from it that you can see faintly, but I don’t know how. So far I’ve been only using materials and a particle system to get the results you see below. So I was thinking of maybe using a fire+smoke simulation to get better results, where the core would be a white ball of fire, and the emitted smoke those energy thingies. But I don’t know how. Or maybe you have better ideas to solve this problem. So any help is greatly appreciated!
