Particular – Motion Path Light with a Light Emitter?
Hi CC,
I’ve built a kind of cool looking beanstalk snake-like particle emitter from a light.
My dilemma is that I need this light emitter to follow a motion path. So now I have two lights, one as an emitter and one as a motion path.
How can something like this work so my two lights aren’t “crossing the streams”? I put the two together and am currently getting a confused system.
Thanks a bunch for any feedback.

Can you upload the image of what you want so that it will be more clear?

I should do that from now on huh?
Here’s a picture that kind of shows what I’m trying to do.
I have a light emitter growing out a “vine” from a light at about 108 degrees. I’d like the tip of the tentacle to follow a point so I figure a motion path is the way to go but I’m finding a disconnect on how to do that using two lights.
Is this possible? Thanks for any suggestions! 🙂

May be this tutorial will help:

You can use the Particular Preset for the veins you are going to create.

That looks really cool, but I’m trying to use a light as an emitter and as a motion path. Also, I’m just using one vein that I’m going to spread to fill the light in the window. Am I just over-doing things? It seems from what I’m reading and watching that I can’t do both. In that tutorial Harry Frank has a Motion Path sequence but it moves along with the path.
I’m trying to emit particles from one point and then use another point as the tip that leads the tentacle. Am what I’m doing trying to use two light emitters make sense?
Either way that tutorial looks amazing. Love what he’s doing with the shading, thanks for the reference. I’ll have to check it out.
Thanks Vishesh!

I don’t know about using Two Light Emitters in this way.
If you use two lights at a time, then both of them will emit particles at the same time.
You want one(at floor) light to emit particles and the Other light to give the direction to the particles emitted by light 1? Am I right?

Yes, exactly. I’m trying to emit from one light source and use a second one a motion guide. Cuz as I understand it I need a light to do both really. I don’t want my emitter to follow the motion path. I want it to stay in one place but have the front of the particle stream follow a point.
Know what I mean? What’s an easy way to do that?
Thanks Vishesh, 🙂

Try to use One light with life and Air resistance to a high value so the particles will remain to their original position.
Animate the light from floor to where you want to move it.
Can’t say anything about using a light to give direction to the particles emitted from another light.

Cool man, will do. I’m also thinking I might trying experimenting with null objects but it’s late over here.
Thanks again!

But I too will do some experiments on how to achieve this with two lights. Will let you know if something good will come out.

I don’t know of any way to have Particular emit from one point and then follow a different light. Check out this Tutorial where he uses wind to give direction to the particles.
