Metal Spark Shower

Metal Impacts · Volume 1

A fuller shower of warm sparks extends the metallic contact into a longer debris tail.

Use: Grinding or forceful metal contacts.

Top: Original · Fine / smooth. Bottom: Chunky / step 3 · Bold / step 6. Matched preset framing at 60 FPS; select Play to compare.

Niagara asset

• Asset: NS_Hit_MetalSpark_Voxel_Shower
• Shipped path: /Game/VoxelHitPack_Vol01/Systems/MetalSparkHitVoxel/NS_Hit_MetalSpark_Voxel_Shower
• Presentation: Original system with three additional parameter presets.

Supported parameters

Values below are extracted from the shipped system. Colors use linear RGBA; vector components are shown explicitly. Restart after editing, particularly counts and seed values.

Parameter	Type	Shipped default	Hard limits	Behavior and dependencies
User.AnimationFrameStep	Int	1	1–12	1 = smooth. 2-12 = hold each pose for N reference frames at 60 Hz. 3 = 20 poses/sec; 6 = 10. Lifetime is unchanged.
User.BurstRotationVariation	Float	25	0–180	Maximum random yaw of the particle burst, degrees. Enabled when User.Randomize = true.
User.Color	Linear RGBA	{“r”:1,“g”:0.42,“b”:0.08,“a”:1}	No exposed bound	Main tint of sparks, embers and ring. Flash core stays whiter.
User.DustCount	Int	60	≥ 0	Number of small glowing ember dots that float upward.
User.Gravity	Float	0.65	No exposed bound	Gravity multiplier for the main sparks.
User.Intensity	Float	12	≥ 0	Emissive brightness multiplier.
User.RandomizationStrength	Float	1	0–1	Master variation strength, clamped 0..1; 0 preserves authored appearance. Enabled when User.Randomize = true.
User.Randomize	Bool	true	No exposed bound	Enable extra voxel variation. Restart after changing seed or toggle.
User.RandomSeed	Int	0	No exposed bound	0 chooses a fresh variation each activation; nonzero repeats a chosen variation. Restart after editing.
User.Size	Float	0.8	≥ 0	Uniform size multiplier for all sprites.
User.SparkCount	Int	140	≥ 0	Number of main sparks spawned per hit.
User.Speed	Float	1.6	No exposed bound	Multiplier for the initial velocity of sparks and embers.
User.SpreadVariation	Float	0.18	0–0.9	Maximum fractional variation in particle distance from the origin. Enabled when User.Randomize = true.
User.VoxelSizeVariation	Float	0.3	0–0.9	Maximum fractional size variation, clamped 0..0.9. Enabled when User.Randomize = true.

No exposed bound means no bound was recorded in the asset metadata; it is not a recommended operating range. Begin with the shipped values. See units and editing, stepping, and layer lifetime caps.

Exact demo overrides

These are four instances of this system. Unlisted controls inherit their asset defaults. All three additional presets are parameter variations, not additional system assets.

Parameter	Original	Fine / smooth	Chunky / step 3	Bold / step 6
RandomSeed	41	41	41	41
AnimationFrameStep	1	1	3	6
Size	0.8	0.52	1.28	0.92
Speed	Inherited	1.76	1.28	2.08
Intensity	Inherited	10.2	12	13.44
