If i need two different object irradiated by laser bean, should I place Obj Info on both and use mix shader to combine the origin material and the irradiated part?

[@emmanuelsaie7882]

Great tutorial. Definitely loved it. Just a little advice. Please be considerate where you put the subtitle. It's kind of hard to read in the upper left corner, especially when paused. Great video once again :)

[@OctopusEffects]

Thanks for your notes. I will consider where to put the subtitles to make it more convenient for viewers

[@ailisnelis2383]

is it working for everyone w cycles?

[@Son-of-Malice]

nice tutorial, for an alternate instead of geo node you can actually replace it with an actual spotlight so its re useable

[@egzongashi9753]

can i make it in blender 4.0 cuz is not showing the same thing?

[@creasedaf1s900]

@ 5:18 I made it to this part , why does the texture just jump to a new one without switching slots or seeing the material for lasers ?

[@masterbae3D]

this is great, but it fail since "attribute" step, its not working in 3.6, may I know if you have a new solution?

[@Nidhichirania02]

how to add laser trail on this?

[@carlospaixao3242]

Evee or cy?

[@ailisnelis2383]

Could you please upload blend file, i've been trying to crack this but it's not happening..

[@LifeBloodMarketing]

Effect worked great, blender 3.6.5, but like others, rendering with alpha doesn't seem to be an option (something with emission and rendering). Does your render have alpha or a black background added?

[@jamesriley5057]

Are you using evee?

[@js100serch]

I didn't understand the #frame thingy.

[@RebelliousTreecko]

Copied the geometry nodes settings perfectly, but the effect is not at where the beam intersects with the ground. What happened?

[@OctopusEffects]

I'm not sure but it could be because your Geometry Nodes are on Displacement in the Modifier tab of Ground.

[@user-zs4iv3vf5m]

I tried the tutorial, may I make something wrong step from 5.24 that the ray did not trace the plane01 move :P, even that , I still learn a lot skill on it and very enjoy the detail tutorial, thank you so much for great sharing!!

[@OctopusEffects]

I'm glad it helps you. Thank you for your kind words
About your problem: I'm pretty sure in the Object Info node you haven't switched to Relative at 4:53

[@vefero92]

thanks, that was exactly my mistake
Great tutorial 👍@@OctopusEffects

[@crgaijin8430]

surface edit not working properly. it doesnt glow on the ground where the laser hits. help

[@designproductwithbing]

be attention, do not collapse the top two point into single one , otherwise, you cant subdivided the faces...

[@LifeBloodMarketing]

Shift+left mouse click, each of the four corners then you can subdivide, instead of selecting the "face".

[@fzigunov]

The "Geometry Proximity" nodee shown in 5:04 does not exist in my Blender (2.93) =/

[@Zephyrleohc]

u should open the page on the menu

[@txnmyn6538]

I also donˋt see Geomerty Proximate, what do you mean open on the menu?

[@zferp]

i cant render the laser in alpha eevee

[@forrest4trees]

You may have to change the blend mode.

[@LifeBloodMarketing]

@@forrest4trees It's something to do with "emission", lots of people asking the same thing with other effects that use emission.

[@email7919]

Are you making a laser or a farm

[@Albighhorian]

this is terrible....

[@OctopusEffects]

Why?? :(

[@Albighhorian]

I was expecting spoken instructions as those would be helpful in the future
