Trying to make something like those laser lights.
For the laser itself i found a lot of stuff on youtube, but when it comes to the details im not sure. Its just consistent in those tutorials when it comes to the beam. But i want some variations like it is in the pictures. The fourth picture is a really good ref, so you can see the smoke/variation in the light a lot. Would be interested to do this in Eevee & cycles just to learn from it.
