I've been trying to find tutorials out there that at least have a similar result to what I'm looking for, but I've failed to find anything close enough. I have some experience with particles and cycles, but not enough to find a way to do this on my own. I'm trying to replicate this specific variant.
What would be the best way to recreate this? Any help would be greatly appreciated.
*UPDATE- I managed to make this using volumetric scattering and emission. It's close to what I'm looking for, but I need to make it flow in a specific direction, similar to what is shown in the video I linked. I've attempted using particles and smoke (smoke was a massive headache for me), but haven't gotten any successful results. This is for a film project I plan on working in the future, and is going to be used as VFX rather than a still image.
*FINAL UPDATE- I've finally found a result that satisfied me. I abandoned the 2001 style atomic breath and went with the 2002-2004 breath. What I did was create a cylinder, make it have a short shape key, and a long shape key, and use quick smoke. I make the cylinder share a material with the smoke domain to make it "invisible" in the render (could create a new material but I was just lazy.) I used the fire sim, and In the node editor, set the flame emission like so. Almost done. To make the the breath flow, I created a wind force, running prefectly along with the cylinder, and parented it to it. Adjust the strength to your desire. Finally, I set the flame to dissolve over time. The dissolve time depends on the length of the cylinder, so there's no set number. There is likely a much better for the flowing movement, but I am still very new to blender, and it works for now. Thank you for the tips and suggestions, I will centainly use them for future work. Here's the final result.
