How do I make Laser Beam?
Hello all,
I want to make a laser beam that will cast intense light onto objects and for the beam to be visible at the very least. Also to reflect off mirrored objects would be great. E.g. a mirror in its path set at 45º should mean the light changes angle by 90º.
I am playing with a narrow beamed spot light using visible light, but this doesn’t reflect and continue onwards at 90º.
I also tried volumetric light through a shaped gobo (hole) which has the same problem.
–> So ideally some help on the above would make me happy
BUT for an encore if you can answer this:
In an ideal world to act like a prism comme ça: https://www.youtube.com/watch?v=qKBu5HVuFQM
…I am aware that the reference may well be live action so perhaps its not possible 😉
Thanks in advance!

You would have to use caustics to have the light bounce, but I don’t think that actually works with volumetric light (can’t remember for sure).

Thanks for replying Adam, I will have a look at caustics, but that word puts fear in me as I seem to remember they take aeons to render and to get right 🙂
I may also check out this 2.5D plugin which seems to show promise and you / anyone who ends up on this post may find interesting:

Looks like a cool plugin, but there are lots of ways you could fake the effect — like using separate visible lights for each “bounce”.
