Hardspace: Shipbreaker Tech Talk: Explosions with VFX Graph
summary
Unity Visual Effect Graph drives explosions with exposed parameters and code: Size 1–5 remaps to particle counts per system (example: 200–1,000 particles via a Remap Float), Color uses a Gradient, Speed is set from Rigidbody magnitude and applied as Z force after Quaternion.LookRotation. Events pick which sub-systems play so one VFX prefab produces four explosion types (Fire, Cryo, Electric, FuelX); Electric caps at ≤2 m and the system works in-engine with ScriptableObject data reuse and Shader.PropertyToID for efficient parameter setting.
