How can one create a laser light [single beam of light, same size whole distance] in Blender. I know there were a few tutorials on this, but they all seem to be gone now. Can someone please help? Thanks
What I would do is create a plane, delete 2 vertices, (on the same edge) so you end up deleting 3 edges. You end up with 2 vertices connected by an edge. Subdivide that several times, then in Materials, press “Halo” the blue button in a vertical column of buttons. Fiddle with the settings, maybe do “Lines” to make it look cool.
Hope this helps,
Depending on the distance involved - you can also use a spotlight with halo turned on… and spotlight sizes brought down to the minimums…
Thanks, I will try the plane and halo trick.
I did try a spotlite with halo, but that creates a light that does grow in size, and the starting point is barely visible.
A single segment with a halo needs to be subdivided a LOT of times to hav halos blend nicely, and you have to tweak alpha and add a lot before having something decent.
Try a plain long, thin rectangle properly oriented with a blend alpha texture on it.
Why not just ADD >> MESH >> CYLINDER?
Give it an alpha, red or green color and some emit?
one long thin line, with wire turned on, two verticies, a face between them… wire and colour is red… simple
