Smoke Texture and Geo UE4

Personal Work
1

Hey everyone! I wanted to share this with yall on how I made this smokey VFX
It is a fairly simple geo, with a texture scrolling throw it.
Scale over time, and a dissolve fakes how it dies out near the end.

Geo: simple Tube shape, with vertex alpha:

Smoke Texture: flame painter is a great start! but i normally repaint most of it out, because it is often a bit too realistic or noisy

Material setup: the dynamic param is to control the random UV offset that gives it a bit more of random look to each geo that spawns. The random speed on the UV pan, also gives it a nice random “rotation” as the UVs pan slightly to in the right.

I absolutely love this solution! It looks way cleaner than some other stuff Ive seen using ribbons or trail emitters. Thanks for sharing!

P.s. I may experiment with this technique for fun. I hope you dont mind!

Great job man. Your stuff is getting real good. I had to double take when I saw your name. Came across this and showed Platt. It was not until later that I saw who made it. Reverse fresnel I love it. Keep up the good work and hope you are doing well.
