Building High-End Gameplay Effects with Blueprint

Epic's Chris Murphy explores how Unreal Engine's Blueprint allows developers to create high-end effects that impact many areas of the game environment without necessarily requiring in-depth knowledge in each discipline.
By leveraging Blueprint as a tool to connect particle systems, render targets and modify assets in the world, this session will allow you to develop a single high-end laser effect that carves through the landscape.

Can't believe he explained all of that in less than 30min and I actually got all of it. Amazing job Chris!!!

[@crazedfan070589]

He has a course on Udemy as well. Really great stuff there.

[@DannyBoy443]

It's just me but I think he was going too fast and is a little bit of a jerk.

[@yoman9446]

@@crazedfan070589 That course sucks balls. He doesn't explain things and just goes "Now I do this then that" Pathetic instructor

I didn't get anything. He skipped steps before he started.

This guy would skyrocket in ue4 development popularity if he started a tutorial series. He knows EXACTLY what he is doing and it's insane

[@theblacktiger59]

Those live stream could be more like that : prepared, straight to the point. Great lesson.

[@fabianoperes2155]

Nope. I think if he does it live it helps a lot more to learn how it was done.

Tell Me About It lol

[@cosmotect]

Oh my god, can you imagine how fun this stuff is when you know all the tools well? You can craft ANYTHIIIIING

[@yonjuunininjin]

This is the stuff I want to see on the Unreal Engine livestreams, even though I knew the technique from another youtube guy who used Rendertargets on a landscape to deform snow. However, this is also another great example with a well explanation. Thanks Chris!

[@ArtThouLivid]

Don't know a thing about this stuff, and i still watched the whole video. I guess this guy is good at his job.

[@fuwaneko]

I understood more about FX and how blueprints work than from the official documentation. Bravo.

[@iancruz3123]

Dmitri Oesa ahaha I feel you

[@Ben-rz9cf]

official docs are essentially worthless. basically, oh, so what does this node do? "quantum vector explosion" hmm, that sounds complicated, better check in the documentation... oh, it says it "explodes a quantum vector". That explains literally nothing and uses the exact same amount of words as the node itself in a different order. Thanks epic, for making that clear xD

[@lokhz9876]

i had to pause this, and say thank you, i dont this guy, but it's the first time an unreal engine's video do exactly what we expect you to do: teach. thank you sir

[@golddeagle7]

[@thedoublep434]

Great job at explaining this, I wish all the tutorials were this fast paced :D

Great tip about "Call in Editor" for Custom Events like this. Never knew that :)

[@swinny_]

I know right. that functionality is *amazing*

[@PsyCoCinematics]

Woooow. That took way, waaaay too long to fix: If you are having issues starting at 9:55 with the logo appearing in the corner(s), it's not a clamp issue. It's not even a texture issue. Move the Landscape to 0,0,0. Tada. Saved you a few hours.

[@maxime3702]

Hi, for those watching this video and attempting to do the same thing on your project, if you are using a more recent version of Unreal Engine (I'm using UE5.4 currently), you may encounter a weird behavior where the texture (and the landscape in result) becomes all white. This is due to your brush material (M_RT_Brush in the video). In the video, when he creates the material, the base color of the material is completely black. In more recent versions of Unreal, the default color of a new material is set to RGB(0.5.., 0.5.., 0.5..) (at least in 5.4), so NOT black but more like gray. Add a constant vector 3, make it black and plug it to the base color of the M_RT_Brush attribute node. And think of me if this comment helped you because I just lost 20 hours of my total lifetime trying to figure out why this kept problem kept happening.

I would love to see how to apply this to the “boy and his kite” demo (the landscape material). I can’t seem to apply this effect to the landscape material at all.

[@songzep5314]

This is so cool!

[@paulspalace4233]

This is awesome! any idea how to make it so the lava that pre-exist on the map doesn't flow into the newly generated lava being created on the map ?

[@JonMW]

Conceptually... you need a brush that works like ink flowing smoothly from a central point rather than applying itself evenly over a wide area.

[@KillerSneak]

So how would one do this for none uniform sizes if it’s not the magic 50400 number?

Every time I watch one of these, it sounds like they set up unannounced in a mall and just started presenting to a bunch of people that have no interest.

[@CyberWolf755]

fast and smooth... mostly :D

[@DannyBoy443]

Actually, Chris, most of us that are new to this, and wanting to learn VFX, not land, are looking at those weird box/nodes and wondering what those are in the first place.

[@PubGamesAU]

docs.unrealengine.com/en-us/Engine/Blueprints/GettingStarted might be a better place to start. This talk was aimed at developers with an understanding of the basic tools. If you'd like more information I'd suggest checking out the samples available in the Learn Tab. For VFX in particular I'd suggest looking at the Effects cave and the Content Examples.

[@DannyBoy443]

Sounds good. I'm an artist and animator not a developer. Thanks.

[@TheHypeaversion]

Does anyone know what those two nodes are that he has plugged into the landscape coords, the ML_Dirt are they custom material functions ?

[@Cpt.Tripps]

Yes. ML stands for Material Layer and is just a material function. It might change quite a bit in the future, now with the new Material Layer system introduced in 4.19 (experimental), where you have actual Material Layer assets, not just functions named that way.

[@TheHypeaversion]

ah thanks for that man, so is it essentially just a material made into a function so it can be called in a material such as that?

[@Cpt.Tripps]

Exactly that.

[@thedoublep434]

How can I create a material that contains meshes? like the grass in this video

[@Cpt.Tripps]

I think this video is exactly about that: kzbin.info/www/bejne/aorRi3tuopyhbNE

[@Sapphew]

He says it'll be in learn tab and content examples but there's no such material.

[@danielvutran]

[@krypto61]

I've got a question: I'm since almost 2 years in Blender and now I wanted to start gaming with either Unity or Unreal and until now I thought I would try Unity. I wanted to learn coding in C# and I know it will get hard but I never wanted to use Blueprints so Unity would be the choice (I thought). NOW I watched this video and it seems that Unreals material/blueprints are quite what I would like more and they seems to be like handy nodes but I'm not sure...can anybody recommend or give advice? :D

[@TimothyBell90]

Krypto any particular reason you didn't want to learn Blueprints?

[@krypto61]

I heard it's easier than real coding but more limited but I dont know if this is true

[@j-art8229]

iirc 99% of the things you could do in engine code can be accomplished via blueprints (for gameplay purposes anyways). However it will run significantly slower than if it was coded in C++

[@krypto61]

J-Art I think I need more comparison between both engines and what fits better into my workflow. Any neutral recommendation?

[@PubGamesAU]

Blueprints are damn easy and super effective for gameplay logic and such. If you're going to be doing engine work or anything super intensive you'll likely need C++ in the long run but you can certainly do a lot with Blueprint. I'd honestly recommend trying it and see which walls you hit and going from there!

[@fenfire3824]

It is very interesting and working well. Actually i like it, but still i have some critics about it. In my opinion, it is just a "make it work" but not realy an overhaul solution. I think if you would like to have effects like this one, you should think about creating a well structured architecture and optimize all your basic maps where yours inherit from. I experienced having a well organized and planned architecture for shaders is important for a good performance. Hope it didn't sound too precocious, just wanted to add some "keep in mind stuff"

[@SansP3ur]

It all makes sense... except, who in the heck is "Zed".?
