Damn. Computers are wacky
No, it’s just blender.
(laughs in horrific blender flashbacks)
I wouldn’t say they’re wacky, they’re just completely inflexible. Every time you find a thing in a computer where you can do something slightly different ways and still get the same predictable output, a programmer had to specially put that in.
@@WilburJaywrightdidnt realize 😢
As a technical artist, I usually approach it differently, but I must say, this method works quite well! It's surprisingly efficient and customizable. The only downside I can think of is that skeletons/bone mesh will impact draw call batching which could be noticable on mobile games if you have groups of soldiers.
Yeah, I don't think this is really designed for out of blender use, though. There's Def easier ways to achieve this in game engines
I do want to say I learned the technique from a gamedev who complained on Twitter about the Vfx work she was doing in-game
What approach do you use?
@@rmt3589 If I wanted it to look like this I'd use a Ribbon particle setup.
@@IIStaffyII Ty so much! Gonna look this up!
I love absorbing Blender knowledge through little bits and pieces like this
I have absolutely no idea whats goin on but awesome
wasn't expecting to hear some ape escape music today
YES! THANK YOU!
U EXPLAIN SO WELL HOLLY
I needed this so badly thank you 🙏🏾
Thats a Lot of Steps xD
The goal is that the trail mesh stretches between the moving sword, and an empty that has the same motions of the moving sword, but slightly delayed.
@@WilburJaywrightstill alot of steps gss
Great tutorial 😮😮😮
I like your funny words magic man!
Wow so cool I wanted to
I remember seeing a similar method to this on twitter
Yes that's the one I used and showcased here
Idk why people seem to think this is a day 1 blender course or something
Cool
Comment for the trailgorithm
The trailgorithm giveth today 🙏
Bruh I love your channel but this feels like way too much to process from a short 😂
In roblox: Add two attachments and a trail object, done.
Bro THE BACKGROUND MUSIC
Is that from Ape Escape ?!
Yep
Thank you, i didn't understand a single thing
Hmm let me see:
Make and Array of Bones > Use Modifier "Target Constrain > Influence Added by 25% *0-25-50-75-100
Step Two > Compress the Bones and Mesh to 1 "Point"
Step three Confusing... Coin too fast even for me xD.
The last step was optional 😅
I kinda just crunched to fit it in, basically it was a way to create the trail effect without hand animating it. The motion of the base bone is baked onto the empty, and from there you offset the animation in time so when you constrain the tail of the motion trail to them empty, it creates a trailing effect
This was my same question, so I started ratting the comment
So basically it means that the animation path is baked to the last bone, chopped from tail bone and offset in timeline, to follow, creating a trail effect.....
Intresting, gotta try out
Thanks for your help 😃
This is why we have addons for trail generation. It’s a lot of hassle. Also for the people asking about this in game engines: it’s a lot easier as you can script the trail behavior and unity and unreal have default systems for these types of VFX
What addon 👀
@@TheSicklyWizard mesh trails for example
. . . *ping
Thats some fancy words you got there magic man.
Never going to complain about delayed release of a videogame again 🙏🏻
He did it all in a short
Yea, not to mention this was a demonstration for making this in blender, not in a game engine where these things are typically made instead
Could this also be done in-engine using shaders?
I believe so
Yes
Ape escape music??
share your Blemder theme 😤 please 😩
Its called emerald from this themes pack on GitHub
github.com/kame404/blender-themes/blob/main/README.md
I don't understand how you got theks circle armature on your plane
How is there not a distribute spacing button...
Personally I prefer to do this effect in géométrie nods
I'd love to know how, I've not seen a tutorial for it 👀
@@TheSicklyWizard Hmmm if I remember correctly, I think I saw this technique in a Cartesian caramel's live

This short went so fucking fast it killed my passion for everything. Just chill, man, people need to digest first
It’s not for beginners
@Jackal_Neck
It is not, I wouldn't recommend it to someone first learning blender 😅
That a subject for a 10 min video 😂
I probably should
Me who watches but don't understand how to code 🗿
Coding is not needed to use blender.
That would only be if you needed to run custom scripts to do things like add additional menus.
Really Coding in blender is something you'd only do if you were making an add on.
To be fair this guy made it way more complicated than necessary
What aspects of what I did do you think was unnecessary?
@@TheSicklyWizard u did a good job I don't know what the guy is talking about great tutorial btw !
@@TheSicklyWizardno worries dude, that guy is just yapping, I literally don’t see any other way to do this other than maybe some janky cloth simulation or a geometry nodes setup that someone else made 😂
Is it worth doing this in blender if you're going to import the assets to a game engine?
It would depend, I don't consider myself a game dev but this technique I showed off in the video I did learn from a gamedev on twitter, @LezTusi. The reason they gave was a.) it cut out the Vfx work out of the workflow b.) gave full control over the arc, that the procedural effect didn't.
I don't know how it would affect performance, but it is pretty simple.
can I apply this to bullet trail FX?
I mean, you could, but since bullets typically travel in a linear direction and don't really swing you'd be better off just having a blend key of a trail that's part of the bullet object if you want something simple
Wouldn't you normally use a particle?
You definitely can, I think this method is a bit more simple than doing a particle
would this also translate to game engines like unreal engine?
Im pretty sure it would work. But I don't use unreal
Ai Ian Hubert?
This hurts on many levels
And that's-
This isn't how you do this for gamedev this is a super expensive way to do trail effects.
I will preface by saying this is a technique I learned from an actual game dev and they were using it because they wanted to have direct control over the motion trail of a sword swing ingame. Conversely id argue it's actually less expensive to do it this way as the trail is a baked effect and not procedurally generated particle system in game which is computationally more expensive, at least as I understand it. The problem with this approach however is it's not dynamic and requires you to actively animate the motion trail yourself. This is a, perhaps, antiquated way to approach the problem, but it is a solution that does work and does have a use case.
Honestly depends on alot, usually particals work better but I don't see why it would be all that expensive
Wow that was… WAY TOO FAST!
no u dont do that u do those things in unreal engine :I
This is blender, Not unreal.
