You could separate/offset the red and green in the shader as well as flicker the image in shader using a dynamic property and noise for flicker amount. Then you could just use one light. It would be much, much cheaper.
Top tutorial that deserve like and sub! 2 question: can the same process be applied with a rectangular light? If I want to have more than one projector with different images is there an easy way to duplicate and change the image instead of rebuilding the whole BluePrint? Super well done
you cant, the rect light works differently and you cant change both horizontal and vertical barn door individually because whatever moron that designed it made it that way, now the barn door angle is broken since it doesn't maintain its aspect ratio, if you have a rectangle it turns into a perfect square once you try to change the angle, so in other words, it can never be like an actual projector that increases in size.
hello, how does this work with ue5? im getting a problem saying that double floats wont work or something and im not sure how to make it single float for it to work with this method
Sure can :) I'm working on a video where I address a bunch of questions at once from all my videos so far, and this is something I'll be covering. Thanks!
Hi!!! amazing tutorial! but i have one question: how did you manage to make the texture colored at first? for me, it's looking on a black and white scale. thanks for sharing your knowledge!
Hey @underscore, I am working on an ancient architecture viz. project. I want to simulate projected video walls as an art installation. In Unity i would simple make a light project the image as emissive light path. BUT Im struggling in UE. I followed your solution but the image remains black and white. Though I can split the lights into RGB properly. What am I missing? Do you have any intel?
thats amazing yet so simple. thanks a lot !
Really amazed at how simple you managed to make this blueprint mate! Thanks a lot for the tutorial!
It's awesome! Thank you, man. Now I'll do something similar in my project ...
WoopWoop! Awesome quick and clear tutorial. Just what I needed:)
is it possible with a video file instead of a image file ?
I was looking for this to make an art project. Thank you so much!!

this is so brilliant ! thanks so much man !
just what i needed!!! many thanks! ^__^ Can it be used with video instead of a picture?
Woow! Cool.
I had an question, how can I project a Rectangular Image like that? whenever I use Spotlight I'm getting a Circular Image projection

HI
May I ask how to make the projector show up image in rectangle shape?
you cant, the rect light works differently and you cant change both horizontal and vertical barn door individually because whatever moron that designed it made it that way, now the barn door angle is broken since it doesn't maintain its aspect ratio, if you have a rectangle it turns into a perfect square once you try to change the angle, so in other words, it can never be like an actual projector that increases in size.
great tutorial thanks!
Youre welcome! :D
Thanks a lot, this video saves my life.
Amazing.. thank u so much for the tutorial!👍
thank you very much.
Thanks a lot
Hey I only get a black and white result. Where did I miss it?
hello, how does this work with ue5? im getting a problem saying that double floats wont work or something and im not sure how to make it single float for it to work with this method
hi! Excellent video!!
Excuse, but its some how make the light cone looks rectangular? Just like a real projector
Hello. Did you find that information?
Great video so professional
But can you do one with a video instead of an image.. Like a movie projector. Or an effect from a TV casting light..
Sure can :) I'm working on a video where I address a bunch of questions at once from all my videos so far, and this is something I'll be covering. Thanks!
@@underscore00Did you ever get around to making this video?

Thank youuuuu I needed chroma to add to my water caustics and I've been trying to make it work for 3 days xD
I have a problem if I output the projected picture through the material

It's just black and white for me, can't get it to show colours
how to get it to work with es2 setting?
uhhhh did I get the right RUclipsr?
um... Yes? :)
