Hi,

if you are referring to this thread:

at that time there wasn't a geometry light in Houdini (at least I think so), so I faked it instancing a light to the points along the laser... for my purposes it did the job, now could be more interesting try the new geometry lights.

Sorry if I didn't attach you any hip file, but as you can see it's really easy to do it...

- just create a light,

- in your geometry (your laser line) make visible the instance tab

- and toggle on the point instancing and connect your light there.

Hope that helps.

Cheers,

Emanuele

A line area-light works well too, especially if you surround it with fog.

Other things to try would be a tube with emission switched on in the shader.

Or, best perhaps to do it in post.

By coincidence I just did such an effect here:

thanks for reply, i did it as you say but what about shader , i use the glow shader , in your project

you use the glow also or other shader .

macha

you mean i must use an area light instide of point light.

it is just cool your effect.
