Heavy

Physical Impacts · Volume 1

A broad luminous arc and dense voxel fragments create a large, forceful contact with a bright trailing silhouette.

Use: heavy feedback in combat.

• Presentation: Original system with three additional parameter presets.

Heavy control walkthrough

The Volume 1 showcase ends with eight comparisons: Size, Speed, Intensity, Color, AnimationFrameStep, VoxelSizeVariation, SpreadVariation and BurstRotationVariation. Heavy is separate from Heavy Slam.

Direct Niagara simulation verifies that BurstCount changes the main spark count and MoteCount changes the floating ember count. Restart after changing them. The unused legacy SparkCount and DustCount controls were removed during release preparation; the default effect appearance is preserved.

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.BurstCount	Int	48	≥ 0	Main outward spark count. Also drives accent bits at half the count, with a minimum of one accent bit. Restart after editing.
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.Gravity	Float	1	No exposed bound	Gravity multiplier for the main sparks.
User.Intensity	Float	12	≥ 0	Emissive brightness multiplier.
User.MoteCount	Int	65	≥ 0	Number of floating ember voxels. Set to 0 to disable this layer; restart after editing.
User.MoteDriftX	Float	0	No exposed bound	Sideways drift speed of floating voxels along X. Requires MoteCount > 0.
User.MoteDriftY	Float	0	No exposed bound	Sideways drift speed of floating voxels along Y. Requires MoteCount > 0.
User.MoteGridSize	Float	3	≥ 0	Snaps floating voxel positions to a world grid of this size in units (e.g. 4 = voxel-grid jumps). 0 = no snapping. Requires MoteCount > 0.
User.MoteLifetime	Float	1	No exposed bound	Lifetime multiplier of the floating voxels. Requires MoteCount > 0.
User.MoteRise	Float	90	No exposed bound	Upward acceleration of floating voxels (negative = sink). Requires MoteCount > 0.
User.MoteStepRate	Float	8	No exposed bound	Choppy/stop-motion movement of the floating voxels: position updates per second (e.g. 8 = mechanical steps). 0 = smooth. Requires MoteCount > 0.
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.SecondaryColor	Linear RGBA	{“r”:1,“g”:0.9,“b”:0.6,“a”:1}	No exposed bound	Hot core / highlight color blended into the voxel centers.
User.ShardGravity	Float	0.8	No exposed bound	Gravity multiplier for shards and accent bits.
User.Size	Float	1.8	≥ 0	Uniform size multiplier for all sprites.
User.Speed	Float	1.45	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	1.8	1.17	2.88	2.07
Speed	Inherited	1.595	1.16	1.885
Intensity	Inherited	10.2	12	13.44
