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.

    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

    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.

    Ah, just after I posted I figured it out. Force field, curve path, check Path Animation in curve edit panel. But yes, the particles are not interpolated, not the emitter. Hope that gets fixed.

    I used to be able to get particles to follow a path in 2.49, but cannot get it to work in 2.58. Any ideas on that?

    Best tutorial. Thank you very

    Hey tarik - crouch is working on an update for the motion trail addon that should be ready in about two weeks - I hope that fixes the issues with 2.58!

    blender 2.58 was unstable with Motion Trail, too much crashes.
    and i have trouble on "writing" a hand made text. it was not easy, but i did finished.

    Thank you for all your tutorials, and for quick replies.
    i also try to follow http://www.blenderguru.com (Andrew Price). He is also good at this blender 3d.
