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.
