Hey!
How would I go about making 3D beams?

i dont understand like beams but they have a 3d look to them or…? something else.

I just don’t want a beam to be like an image…

oh so 3d look for that follow these steps:
Step 1: get the origin and destination
Step 2: C O D E
local start,dest
local p = Instance.new("Part")
p.CFrame = CFrame.new(start:Lerp(dest,0.5),dest)
p.Size = Vector3.new((start-dest).Magnitude,1,1)
p.Anchored = true
p.CanCollide = false
p.Parent = workspace

What is that code…? And what does it do?
Edit: I don’t think that’ll work. It just creates a part and the size will be start-dest.magnitude and etc. Though the start and the destination isn’t even set. Also, It’s a beam, not a part…

Check the documentation:
Beam | Roblox Creator Documentation
You can do all sorts of effects with them.
What are you trying to use this beam for? A gun, an explosion, a sun flare?
If you give us a good description of what you are trying to accomplish we can help you better.

It’s for a bullet for a gun system:
But when I shoot, the beam looks like that because of the face camera:
I just want to make it more realistic by making it 3d, so it actually looks like that:

Kinda. It shouldn’t be a trail though, because I need it on a specific position. It moves with the bullet too.
Why not just model an actual beam?

I don’t know how. Even with a tutorial on blender.

And what about the gradient, the brightness and all that kind of staff? And transparency?

You could try using multiple beams, have a circle of start attachments at one end and another for the end attachments.

That’s exactly what a Trail does. It ‘trails’ behind whatever your object (vehicle, Part, Humanoid etc.) is while moving.
I’ve used it to leave a track behind vehicle wheels that fades out. You can make it stay in place or move with the object.
You can also control the Gradient and Transparency Properties.

I just fixed the issue by adding a part with a color similar to the beam. A 3d beam should be a better feature, but that works for now.

You probably don’t want 3D beams and I’m going to explain you why.
-
Bullets move so fast, nearly not a single person in the world is going to notice that your beam is a flat image.
-
3D models might cost significantly more computing power to render compared to beams. having 100s of bullets all rendered fully 3D might degrade the performance of your game.
-
A 3D model would be mostly static and not animated. Beams and trails can be animated to make bullets look more dynamic and interesting.
If you really want 3D bullets I won’t stop you, you could use parts or a mesh and stretch it from one point to another.
But I don’t think it’s worth the effort in the end if almost no one notices the difference between a 2D and 3D bullet.
The only times I would use 3D bullets personally is if the bullet is either VERY large (like a rocket from a rocket launcher) or a plasma cannon firing a very wide beam for example that pierces through multiple targets.
I hope this info helps.

I’ll agree with you. You’re actually right.
