Hi guys!

I am working on a project that needs a spirit moving through a scene, it needs to be like flowing smoke with a glowing light effect .

I cant work out how to emit light from the smoke and move with the animation, i have been playing with both volume lights and geometry lights but i cant get either to move with the animation, they both stay at where the animation is on frame 1. I have tried selecting the volume and creating a volume light from that, and also using the original animated geometry before it was turned into a volume and making a geometry light from that, but neither use the animation.

Can anyone suggest what i am missing or doing wrong? Or way to get the smoke to emit light and use the animation to move? 

I have attached a r&d scene file and a play-blast of my problem as it stands at the moment, any help would be really appreciated!

On your geometry light; tick on for “Transform Into This Object” - it's right below where the link is to the object your using.

Also as yourself, and I don't know how to change it - you won't see the result in your scene.

But if you do a render you will see the result as expected.

Hi BabaJ

Thank you for the feedback! I have done a quick render with ‘transform into this object’ turned on and it still doesn't seem to be working, i think the light is moving slightly now but it is not emitting from the smoke as such, more just in the scene, do you know a way i can have the main body of smoke glowing from the light as it moves?

I think it's because you have competing light intensities such that you can't see the smokes geolight.

The only thing I've changed in your scened is turn the geolight to ‘yellow’ and turned down/off your other two lights.

Thank you for having a look at my scene BabaJ!

I've managed to get it working, it wasn't really working before because the volume in the pyroImport isn't the actual squab that i'm using, as the smoke has a trail that is slowly evaporating it was recognizing it as one whole entity rather than just the object leading the smoke. I set the object to the fluidSource that is feeding the dopNet and now it just glows up the base volume before it is converted to smoke, this is much more like the effect i was going for. Thank you for all your help!
