I need help to reproduce this kind of bright effect on Blender, but I want to animate it as well, the animation could be it just turning around in circle.

What do I need to search about to recreate this kind of effect ? enter image description here

Thanks in advance

    Depends a little bit on how you want to create it. The "normal" way I'd say is, if you create an animation of emissive particle objects, then in the compositor you can add a Glare node, maybe even combine multiple ones with different settings and mixing them together. The question is, how experienced are you with the compositor, how much advice do you need? – Gordon Brinkmann Jun 24 '21 at 09:12
  • The compositor is really unknown to me. – Gabriel Magalhães Jun 24 '21 at 09:26

    you'll probably find some ideas here: https://blender.stackexchange.com/questions/199172/create-a-trail-effect-meteor you can do it with a mix of material, particles, and compositing – moonboots Jun 24 '21 at 09:36

You can create a comet object that will be made of a ball (the head), a thin tail and a bigger one. Also create a curve, and give your comet object a Curve modifier to make it follow the curve. Create 3 different particles that will be your sparks:

Give your comet and particles this kind of node setup: Emission mixed with Transparent with a Layer Weight as factor, with a gradient on X for the tails, some noise to create texture, push a bit the Emission strength so that it can bloom:

Give your object a Particle System > Emitter in order to create the sparks. In the Compositor give your image a Blur and a Glare node to create the image effects:

  • I've follow your steps, but mine doesn't look quite like yours. How can I show a result in here ?

  • please share your file (copy and paste here the url it will give you once you've uploaded the file): https://pasteall.org/blend/ – moonboots Jun 24 '21 at 12:55

  • it seems to work, you need to give another material to your particles and to your comet itselft, don't give it noise, just pure Emission to begin, then you can try to mix with Transparent with Layer Weight as factor... – moonboots Jun 24 '21 at 13:03
  • if you test the material in Eevee don't forget to go into the Material > Settings > Blend Mode > Alpha Blend in order to have transparency – moonboots Jun 24 '21 at 13:04
  • This is my result, following the steps above https://pasteall.org/pic/e04582bce5304fab9361bac226e6b0ed – Gabriel Magalhães Jun 24 '21 at 13:12
  • so you're not too far, you need to give a rather white color to both the comet itself and to the particles, push up the Emission strength, enable the Bloom option in the Render panel, in the Compositor give your image Blur and Glare – moonboots Jun 24 '21 at 13:17
  • I did what you said, but I'm still getting issues in my render. The result that you got, is exactly what I need, but when I try to reproduce your steps, my result doesn't look even close yours. Could you check my file please? And let me know what is not correct ? That I need to change? I've created a material just to the "ball", another to the tail, another to the dusty, other to particles. I've added blur and glare on composite too, and messed around a lot with this, but nothing close. Can you check it please ?https://blend-exchange.com/b/w5D5Jnr3 – Gabriel Magalhães Jun 25 '21 at 06:53
  • use a lighter (whiter) color for the ball and the thin tail (i.e. lower the saturation value). For the Compositor, click on Backdrop and create an Output > Viewer, an dplug the Glare into the Viewer. V and Alt V to scale the backdrop – moonboots Jun 25 '21 at 07:31
