Hello! I’m coming here to seek some guidance in how to make this Tracer Ammunition work. In this post I’ll try to explain my problem and some possible solutions I’ve found, but any of it works properly like the example
First of all, the Effect I’m seeking is the Tracer from UT 2004, more precisely the Minigun
That’s a nice example that I want to make. So I opened the UT4Editor (the most recent UT) to see if the Tracer in the minigun works like that, but no. It’s just a simple Beam that goes to point A to point B, not a nice bullet travelling to the end.
The effect I desired should be simple to reproduce, but no I guess. The I tried 2 different approaches
Example 1: Mesh with Emissive
The most simple, Creating an egg shaped mesh scaled in the X vector to simulate the Tracer ammunition flying, giving it a sensation of speed, and a glow emissive
But It creates a problem with the bullet speed when I move to the sides. It gets strange if the mesh travels in the air for more than 1 second. And if I add more velocity for the fake projectile, I can’t see it coming off from the muzzle.
I tried to put a Ribbon in it to see some good lines coming from it, but in the end it looks like a line coming out of the Muzzle, not a Bullet
Example 2: Beam Particle with a Scrolling Texture
Then I tried to replicate the Minigun Tarcer effect from UT 2004, creating a Beam Particle (I think it’s the same thing)
My approach should be simple, create a Dynamic Material that controls the Panner time and access it in the Cascade, but it doesn’t work. Somehow the Dynamic Parameter doesn’t work with Beam Particles.
So, how can I control the Panner? Since I can only the Particle Color node inside the Cascade, I just simply working on that like a Dynamic Parameters.
But in the end I need to create a very specific bullet texture to see it coming from the barrel, I can’t really control the distance between Source and Target (The bullet looks ok from far away, but if I shoot a wall with 2 meters of distance I can see the texture Squashed and slowing scrolling out) and sometimes I can’t really see the texture exiting the muzzle.
After trying to fix these problems with no success, I came here to show my work so far and ask if someone could help. Much appreciated.
