Is it possible to make curves glow without making tubes?

[u3000]

I’ve seen videos where people making neon light effect, but they were creating tubes, what if I have bezier curves, could I make them glow? I’ve seen there emission type of material. I would like effect to be seen on Sketchfab, so not sure what to use exactly.

You can’t make a thin curve glow (or visible), at least afaik. You’d have to increase the bevel depth and possibly reduce the resolution under curve geometry. It would still be a curve rather than a mesh.

I was kind of looking for something like that
don’t think it Is possible in cycles

easier to do in EEVEE

see my thread here on LED

EEVEE invisible Emisson mesh?

problem with light path is that the mesh is not seen but the light goes away too! so not really good ! I need like an equivalent mesh light source but not seeing it even using an IES light won’t work cause I cannot put it outside it does not do the right light distribution in space around the LED if you look to my render it is almost good 90 % so still missing a more realist physical render ! but it is better then in cycles! thanks happy bl
