Thats some kind of sorcery i want to have nowadays

This is so well put together. Thank you! Really easy to listen to and follow along.

Great video, thank you. I have a question: how would you handle the precision of the collision for more complex meshes?

Great but hard for beginners like me. If you can explain each node what it does in more details and slower speed...thanks

I loved your voice and telling <3

Sorry to hear about the tough times, thanks for the great content (but take all the time you need) :)

Could this in theory be reproduced using a scratch pad to generate a vector field instead of using a material? Id like to attempt to extend this effect into 3 dimensions.

Great channel! Is there any way to sample the texture from the mesh in local UVW space? My issue is the skeletal mesh I am trying to apply this to has 10 materials...😅

Hey everyone trying on Unreal 5.4, when you get to 11:13, your lightning is going to go crazy because the effect is drawing the beam every single frame. Switch the offset to Random Range Vector and change the Evaluation Type from "Every Frame" to "Spawn Only". I think what's happening is the new default has been changed to draw every single frame but we just want to have it evaluate on spawn. There's probably a cleaner way to do this but I've found this method allows me to get a better result. Awesome video by the way Enrique, keep it up 💪

not getting line trace to work any ideas. really cool work thanks bro

You So Wonderfull Best Guy So Thank you !! I wish You Forever Happy !!!

This video is so amazing. So straight forward and easier than thought. You rock

I see this guy is drawing to a canvas rendertarget multiple times per frame. Last time I did this in unreal, it had a high impact on performance. Can anyone comment on this?

!!!y olé!!!😉😸💞

Hi! How do Iwork with the compute shader? I am trying to find information on how to do that in UE5 /UE4 but can't find anything online. All have now are my uplugin with a module and nearly blank ush and header files.

The expressions are magic！

Hello, I've followed the steps up to 11:36, but my secondary trace is behaving strangely. It doesn't connect with the first trace and instead forms a shape on its own, pointing upwards toward the ceiling. I'm not sure why this is happening.

What a man we have here. Great tech artist

*Error: r.Nanite.AllowTessellation is read only!* What you say about it?

How to use it in sequencer without simulation because it doesn't seem to work when I'm rendering.... Also, I use third peson iny my game so simulating is not the best approach for me

this is perfect for what ive been trying to do. im trying to give my character a stylized flame head, and i found a way in blender with metaballs that looked perfect, but then found that baking the animation in blender caused it to no longer be dynamic. but this fixes all that. Thx!

Thanks @Enrique for your kindness, your tutorials are awesome

Hi Enrique. back at your videos again. i didn't really understand what you did to calcualte shadows based on the distance field. A genuine question: Is it possible to get this shadow mask from the distance fields even without computing through they ray marching? Let's say you have a normal surface, and you want to mask on it the shadow of another object. I'm trying to replicate this rn but i'm struggling to grasp that very part. Thank you in advance, you are great <3

The Colors mixing is a super nice detail. I cant imagine that was an easy task... maybe it was?

Great tutorial, I'm planning to use this starting point to build a whip. Thank you for sharing your knowledge.

In case anyone is having trouble with the code not working, there is a small typo, use this float afwidth = 0.7 * length((DDX(B), (DDY(B)))); return smoothstep(A-afwidth, A*afwidth, B);

Hello, my lightning is thin and just a few segments. How may I add more segments to my lightning and make them thicker?

The effect looks really good and I am grateful for the step-by-step breakdown. Thanks.

Great tutorial. You can likely make the shader a bit faster by replacing the "length(a-b)" with the cheaper expression "dot(a-b,a-b)" which is the square of the distance.

Great effect! Thank you!

Enriquee sacate un curso de Niagara ya por favor lo necesito! Increíble trabajo como siempre!

Hello, nice tutorial, but... no "VolumeBoxIntersect" function in Unreal Engine 5.4, Impossible to follow, and it worries me, that depending on this function may cause future versions to stop clouds from working and if we scale it, it damages the cloud, question: why not a great RayMarching material tutorial like the previous one with absolute world position and atmosphere sunlight, but better quality and not splited by the cube, because that material still works today.

Please how do i get the progress ( how much of the texture has been covered? )

Unfortunately, this doesn't seem to work anymore in 5.4. It seems that Niagara's Beam Emitter Setup has changed and now the vector position information from the event graph doesn't plug into the Beam Start and End positions cleanly. It's insistent on converting the vector into a position instead of just using the vector as a position. I can't seem to find the right settings to make it work.

hello there i would insanely appreciate if you told me how to do this with an actual volume texture node because i found no volume texture node that returns a volume object instead of just uv based rgb

Hola Amigo! Loving this series. Thanks for taking the time! I've been scouring the web all week and this is the first tut that makes sense. I have to ask because I can't find info on it anywhere... Do you know of any resources that go over creating a Pseudo Volume Texture from a mesh? I am very comfortable in Blender, so that would be a bonus! I am wanting to turn models into textures to use as volumes in UE5 for a current project.

thanks a lot i wanted to make my own voxel raytracer and even if this is still perfect

podrias compartir el proyecto buen hombre?

how would i go about changing the strength / opacity of the lines for the shadow??

Hey Enrique, thank you for your amazing content! I made a plugin that does the choppy animation trick with a single node in anim BP. and I would like to share it with you if you have any interest

After populating the grid around 30:47, all my particles are red and not green.. Any idea wha could be wrong?

Wow, coming from blender i wanted to do some water particles and got a bit sad i couldn't get it to work till my brain got some wrinkles and remembered about metaballs in blender :D Happy to see they're a thing in ue5 as well (:

Enrique, thank you so much for this tutorial! I've been a fan of yours for a while. This is one of the videos I've come back to a few times because I have never been able to get it to work. I always get stuck at the point when the scene capture component composite mode is switched to additive. For some reason, the whole mesh starts to slowly fill in with bright emissive white. Is there anything that I might be missing with the way that camera capture is set up? Thanks!

I'd love to learn how to apply some of these effects to a static mesh!

Awesome!👍
