LuxCoreRender Forums

I wondered if creating optic fibers (without faking them) in luxcore was possible. Then I used the ivy gen addon, converted it to mesh, added a plane with emmision material and added a bool modifier to it. Tuned light paths to 256. The ground is a 99% black material, so the camera views the scattered light of the air volume and not much of the ground diffusion.

I tried some fibers too.

This looks interesting. I played around with your scene, really liked the fast resolving reflections that you get around the optic fibers tips.

I probably setup wrong the eye depth to 6 but in the wiki it says: "If your scene contains mostly direct lighting, you may be able get a small speed boost without any detrimental effects by setting this lower than the eye depth". And I wanted to get light to bounce at the glass and then scatter at the air, so I cared most about this value. .
The light is also very strong, but the air scattering is almost realistic ( it's 0.003).So it had to be strong for scattering to appear. (to be sure it appeared I used a simple setup with the same volume, and a simple light with the same strength and nothing else. The scattering appeared ok there).
