Acid burst VFX, developed in Unity's Visual Effect Graph.
The advantage of using a node-based visual effect here is twofold: First, there is no need to manually animate anything with keyframes, saving production time, and second, this effect can be copy and pasted as often as needed, to create visual appeal for explosions, power-ups, opening portals, shields, and so much more!
Shader-based acid burst, great for a portal or combat-sequence VFX. Developed in Unity via the Visual Effect Graph.
