Tutorial: Light Streaks in Blender

Written by  Gottfried Hofmann
Cool looking light streaks are not exclusive to commercial products like AE. In fact, you can create those in Blender as well. With full control over speed and timing thanks to the motion trail addon.

This tutorial shows you how to create light streaks in Blender and how to use the motion trail addon by Crouch for animation. Learn how to use a texture to control particle properties over their lifetime and receive some troubleshooting tips.

    Thats a really cool tutorial. The way you taught how to set up the material was awesome, explanation crystal clear. I loved the way we set up the texture with strand/particle to influence the transparent halo. I'll try to use it for other stuff too.

    Hi Gottfried, Great source of tuts! I was successfully got through Light Streaks in Blender. I am now trying to Incorporate this tut in a new project.
    In the new project the light streak enters the scene orbiting the earth and exits the scene. There is 1300 frames the streak starts at 600 and ends at 1000. I used Animation motion trail to set my path everything works good however there is no streak when it animates. There is something I need to do in the Partials tab. Whe I make a short path it works but not with the long one. Help please.

    This is what I achieved using your tutorial.

    I really loved watching your tutorial.

    I found out how to work with the Follow Path tool in blender to achieve the same effect as the motion trail.

    Just increase the number of frames in the Nurbs Path panel and you're good to go. The possibility to regulate the speed and timing, i don't really know, but it achieves pretty much the same clean and nice streak as using the motion trail does.

    Give it a try.

    Thanks very much for this informative tutorial from you!

    Hey Chris, the motion trail addon only affects the path of the cube emitter :)

  • Comment Link  chris Sunday, 15 July 2012 18:01 posted by chris

    following this tutorial using "curve guides" forcefield settings in blender 2.63. results are just as good exept you cant adjust the speed settings for the particles.

    just one thing the force field i dont know how to turn off, so it doesnt affect particles that appear in later parts of the animation. ( i want an explode effect on a seperate object after the particle finish traveling)

    does this motion trail add on that you have used affect every object in the scene or is it only affecting the path of the cube emmitter

    Very nice and easy to follow tutorial.
    If I might suggest one improvement it would be for you to check the audio levels before uploading. Your voice is so low in amplitude on this recording that it is actually a bit challenging for me to follow at a normal volume setting.
    When working and switching between different videos, audio etc. it is a bit tedious to have to adjust the main computer volume every time I go back to your video.

    It might be just me having this issue because I work in audio, but I thought I would draw your attention to it. If you have no audio experience I would be happy to suggest to you some ways to measure and ensure a better audio side to your videos.

    Thx for all your work in teaching others how to use Blender.

    Hey Rupert, wenn du bei meinem Resultat genau hinkuckst wirst du feststellen, dass sich die Farben da auch addieren. Das ist der "Add"-Effekt des Halo-Materials, den kannst du unter "Add" in den Material-Eigenschaften des Halos justieren.

    Hi Gottfried

    Supertolles Tutorial erstmal. Auf die Idee bin ich nicht von selbst gekommen =) Danke auch für das motion Trail tool und die super Erklärung. Super - Nützlich ^^

    Ich hab im moment allerdings noch nen Problem. Ich weiss nicht obs an der Blender Version liegen könnte, aber immer wenn man hintereinander 2 trails hat mischen sie sich zu einem. Das ist ganz schän nervig wenn du versucht überlappende zu schaffen. Ich weiss nicht wie du es auch in deiner Beispielversion so gut hinbekommen hast das man immer erkennt welcher der teile des trails vorn ist. Ich sag mal wenn man durch nen großen laser schaut soll man die trails dahinter nicht mehr sehen. Bedauerlicherweise addieren sich die Farben für die Kamera. wie haste das hinbekommen?

    Danke für die Hilfe

    Rupert

    Hey Andrius, you can change the color of the background in the world settings :)

    Hi, its very nice tutorial, but I don't know how to make a white background. Maybe someone could help me?
    Thanks.

    just use "clamp to" instead "follow path" contrain,
    ikey start- and endframe while moving along the path with "g",
    then all frame interpolated particles get shown too.

    So, you do not get the "perl chains" like shown in the tutorial but continous light-streaks

    => you can use blender curves instead of the add-on curves (at least in 2.62)

    Hey Chuck, unfortunately the Halo material is not yet implemented in Cycles. So at the moment, this is only working in Blender Internal renderer...

  • Comment Link Chuck Fletcher Wednesday, 28 December 2011 14:43 posted by Chuck Fletcher

    Hi, any idea how to get the streaks to appear with the cycles renderer? It works OK with the blender renderer but I can't see the streaks with cycles. I'm using an emitter but the single vertex particles arent visible.

    Hey 3pointedit, I just checked r39488 and it's still there

  • Comment Link 3pointedit Monday, 15 August 2011 12:27 posted by 3pointedit

    Great tutorial Gotttfried, I was trying it on a recent release (from 14/08/2011) but could not find an alpha value in Halo Texture. So I could not get the streak to fade at the ends. Has the particle/ strand texture changed since you made this tut?

    Hello Simon. Yes I thinking of the same. Use a Bezier curve as follow the path. I try.

    Hi Gottfried and thanks for a cool tutorial

    I tried several times to install your AddOn Motion Trail but it did not work for me

    I would like to write/type my name with this turorial and then do the loop as long than the 150 I need at least about 250 frames. How do I extend it.
    Thanks

    Mikey: Weird, the part you mention is actually an explanation and not a step-by-step-guide. So if you follow it step-by-step you probably will get lost. It requires some basic knowledge of color theory, though. I'm trying to explain a part there that I had not seen covered in other tutorials. I'll try to be clearer or try another explanation in further tutorials on the subject.

    I'd Love to do this tutorial, but it assumes a VERY high degree of texture knowledge. Starting at around 6:30, anyone who hasn't been using blender for many years will get completely lost. There is no mention of what you're doing, or why. It's just - "do this, this this this and then we have this". That section of the tutorial is not for anyone of medium or advanced knowledge of Blender - only experts. It's too bad. I watched that section 8 times, and get lost every time. I appreciate you doing this, but just realize that almost nobody will be able to follow it.
