One of the most valuable 24 mins that I spent in my entire life. Straight to the point, no bullshit talking. Even though I didnt understand some parts, I can have a look at the documents or other videos. This video can easily be referenced later to look for some points. Thanks one more time for not making this tutorial 1 hour long by giving the extra unnecessary information - details - about the parts that you used in this tutorial.

Your content is so good that you're one of the few youtubers for whom I turn the ad block off.

Great tutorial. I had a slight issue with the scrolling part at the beginning. If your laser texture is showing correctly when you set the scrolling speed to 0, but disappears when you set it to anything different, check your laser texture in the project window and make sure the "wrap mode" is set to REPEAT or MIRROR.

Bruh your explanation, even though it was fast, is great. Instead of re-creating the final shader graph from the beginning, you built the final shader step by step (re-creating the links). Thanks for valuable tutorial.

Better course quality than i get in school (DAE #1 global), mad props my man

[dr.mailman]

Thanks for all of this, I like how you have the packages to buy on the asset store but also teach people how to do it themselves.

Hey, for those who wanted to use the line effect in TILED MODE and not STRETCH: You can have pretty much the same fade in/fade out effect without using any mask. Just create 3 segments in total, you can do it in LineRenderer -> Positions -> Size = 4 et the edit z or another axis (something like 0, 0.5, 5.5, 6). So the first segement 0<->0.5 et the last one 5.5<->6 will be used to fade in and out, just put the color gradient's alpha to 0 at the start and end. Obviously you can use this AND a mask.

Amazing thorough video, you deserve many more subscribers, not seeing many people going into this much depth.

[AlanDarkworld]

Very instructive, and an interesting way of using UV movement. Thanks!

[InsignificantIsaac]

The scrolling isn't working for me, i even checked if animated materials were on and it was. What is the problem?

[timurradman]

Had to rewatch it twice to realize that you actually can't control the position of the gradient points. You do change them at 5:08 and that's it. Is there a way to control the color better? Can we have a rainbow color for example? I've been messing around with it for hours and couldn't figure it out

[wholesomedokichannel]

Awesome. These look so professional it's incredible

[michaelbarbour]

Some really good work, thank you. Your tutorials are phenomenally clear and you explain everything really really well. Keep up the good work please.

[abdallahmohamed]

this is an absolutely amazing tutorial with a clear voice and instructions followed by nicely planned structure of information
thank you so much for this tutorial kind sir

[lemetamax]

This is the third and awesome video I've watched here, you've earned a sub!

[Sparrow]

Real nice, thanks for the share.


btw, about the light - you can use the new "tube" light they added, it's perfect for a laser beam.

[calodie]

Your shader tutorials really helps me out! Gonna like all your videos!

Here I got a problem. The tiling of the UV is always 1 and the texture applied to the beam is scaled with the scale (length) of the line. How can I make the texture "repeat" but not "dragged" when the laser beam gets longer?

[Gabriel-nowv]

9:45 What tool did you say that you use? You didn't show it, and I dont understand what you said.

[xanaramus]

Very cool effects, thank you, writing this comment with hope to see your next videos!

How do you open the shader in shader graph? ** nevermind, I didn't have the shader graph package installed. Window > Package Manager... you also need LWRP or HDRP installed... This tutorial really needs to be updated to address rendering pipeline dependencies. If you have an older project and try to update your pipeline you will have many materials' shaders that wil have to be converted in order to work
properly. Thanks for the tutorial though!
