Procedural High Smoke

This is a smoke VFX, rising very high up as an environmental effect within the scene, similar to the smoke from a large fire or a signal fire.

When creating large-scale VFX like this, achieving the desired effect using only physical velocity and forces can be challenging. This approach offers a solution, as the overall silhouette is procedurally generated mostly without relying on physics simulations.
