NEW: 4K WebM videos with alpha. A separate download with a 4096 px, 60 fps VP9 WebM with a transparent background for every animation in this pack. Plays with transparency in OBS, Godot 4, browsers and most video editors.

Limited-time bundle: this pack plus 11 more game VFX packs in the Game VFX Mega Bundle for $54.99 instead of $181.89 (save 69 percent). Or get every SEAMPROOF product for $109.99.

WHAT YOU GET: 10 seamless character auras.

• Each is a 128-frame loop on a tall 2048 x 4096 frame, as sprite sheets plus 256 and 512 px frames.
• Native 4K PNG frames of every aura.
• Unity package (Unity 6, Built-in and URP): sliced sheets, animation clips, prefabs, flipbook shader and demo scenes. Import-tested: all 20 clips checked.

Power-ups that wrap the character instead of sitting on top of it. Overdrive is ten aura animations for 2D games, each a different simulation rather than a recolour, rendered on a tall 2048 x 4096 frame at 60 fps with straight alpha. Every one is a seamless 128-frame loop (2.13 seconds) built around an invisible standing figure: the effect hugs the body, climbs over the head and pools at the feet, and the centre column is left for your sprite, so you draw the aura behind the character and it reads as wrapping around it. Watch the actual delivered animations in the previews.

Ten motions (all 2048 x 4096, 128-frame seamless loops)

• Flame Aura: tongues of ridged fire lick upward around the figure, taller over the head and shorter at the feet, with noise eating the envelope so tongues detach and die, a hot broken rim against the body, a pooled glow at the feet and 300 embers rising and wobbling off the body edge.
• Lightning Aura: a band of static charge crackles on the skin at 30 Hz while seven to ten short arcs crawl along the silhouette, re-formed every two frames, with branches leaping off them; three to five bolts per step jump from the body out into the aura, and 160 sparks orbit the figure on closed paths.
• Void Aura: black smoke, lumpy and opaque, rolls slowly upward around the figure, thicker over the shoulders and thin at the feet, hiding what is behind it. A violet glow burns at the body edge and shows through the gaps, smoke lumps next to it catch its light, and 140 violet motes drift up through it.
• Holy Radiance: soft golden rays fan out from behind the figure, a six-fold set turning one way and an eight-fold set the other, fading in from the body edge so they come from behind the character. A hairline halo in perspective floats over the head, 260 motes rise through the light and fourteen four-point glints twinkle.
• Frost Mist: cold mist sinks down the figure, thin at the head and thickening as it falls, and pools in a flattened cloud at the feet; 90 six-point ice crystals drift down, swaying and turning as they fall, with 320 specks of frost dust.
• Wind Shear: translucent ribbons of air with hairline edges whip upward in a spiral around the figure, brighter where they pass in front and dimmer behind, with 220 dust specks whipped along the same vortex and a faint rim marking the body.
• Rage Aura: jagged red energy, spiked by ridged noise in the angle around the figure, flares in four beats per loop: on each beat a spiked shell bursts outward from the body and dies before the frame edge, cracks of light leap off the silhouette (five to seven per step, fourteen more on the beat) and 120 sparks fly.
• Arcane Sigils: a rune ring in perspective turns once per loop at the feet, a hairline double ring with 48 ticks on the inner ring counter-turning, 18 rune glyphs standing on it blinking on their own clocks, and twelve glints riding the rim; a smaller ring over the head counter-turns twice per loop with eight glints, and 320 violet motes spiral up from one ring to the other.
• Nature Bloom: 64 leaves, each an exact lens with a hairline outline and a midrib, spiral up around the figure on helical paths, turning and foreshortening as they climb, brighter in front and dimmer behind, through 360 soft pollen motes and a soft green glow around the body.
• Shadow Flicker: a dark echo of the silhouette flickers behind the figure at 30 Hz, jumping to a new sideways offset and scale every two frames, sometimes doubled, ragged at the edge and opaque, with a purple hairline rim and glow; a slow drifting ghost of the silhouette stays underneath so the shape never fully vanishes, and 160 purple motes shed off the body.

One figure, ten simulations

Every aura is computed in the coordinates of the same invisible figure (a standing capsule with a head, 0.4 of the frame width across), so they line up with one another and with your sprite. Swap auras on a character and the body stays put. Loops are periodic by construction: every noise field travels a circle in 4-D, every orbit, pulse and spawn clock runs an integer number of cycles per loop, and the 30 Hz re-forming effects are seeded from the frame index modulo the loop, so frame 128 equals frame 0 exactly.

What you get

• 1,280 native RGBA PNG frames (128 per motion), 2048 x 4096 px, straight alpha.
• Sprite sheets at 4096 and 2048 px for every animation: 8 x 4 grids of 512 x 1024 px cells, four sheets per loop.
• Loose 512 px and 256 px sequences, 1080p MP4 previews, GIF previews and contact sheets.
• JSON metadata per animation: frame count, fps, playback mode, pivot, sheet layout; a pack manifest.
• An offline browser viewer for every motion with playback, scrubbing, additive or alpha blend and background checks.
• Godot 4 helper script, Unity and Unreal import notes, a VERIFICATION.txt per animation.

Straight alpha, no dark halo

The colour under fully transparent pixels is bled outward from the effect, so filtering, mipmaps and downscaling never grow a dark fringe. Smaller sizes were produced in linear light on premultiplied colour and un-premultiplied afterwards, then measured.

Measured before packaging

• no frame touches the border
• loops are periodic by construction: frame 0 and frame 128 are byte-identical
• no duplicate consecutive frames
• transparent pixels next to the effect carry the effect's colour, not black

Drop in

Draw the aura behind the character sprite, centred on it, with the figure's feet at 89 percent of the frame height and its crown at 14.5 percent. Unreal: FlipBook node (8 x 4). Unity: Sprite Editor grid slice or Texture Sheet Animation. Godot: the included script or AnimatedSprite2D from sheet. Use alpha blending for Void Aura, Frost Mist and Shadow Flicker (they carry smoke, mist and an opaque echo); additive suits the other seven.
