File multimediali per l'articolo SparkFX Previewer — In-Editor VFX & Animation Workflow Tool: 1

Descrizione

Current Version: v2.3.0 | Unreal Engine 5.6, 5.7 & 5.8

Build, test, and refine animation-driven VFX directly inside the Unreal Editor.

SparkFX Previewer is an editor-only workflow tool for VFX artists, animators, technical artists, and designers working in Unreal Engine.

Preview Niagara effects, character animations, projectiles, trails, audio, and camera shakes in a dedicated editor environment without repeatedly entering Play In Editor (PIE). Synchronize effects with animations, adjust timing, stage characters and props, and export supported animation events as Anim Notifies.

Spend less time setting up tests and more time creating effects.

Key Features

Animation & VFX Timing

  • Preview character animations alongside Niagara effects.

  • Scrub animation and VFX together, with Niagara effects re-evaluated at the selected time.

  • Trigger VFX, audio, projectiles, and camera shakes at precise moments.

  • Work with animation sequences, montages, root motion, and multiple VFX tracks.

Projectile & Impact Testing

  • Preview linear, arc, and ballistic trajectories with gravity, air resistance, and wind.

  • Test rapid fire, bursts, multi-shot spread, muzzle flashes, impacts, and in-flight VFX.

  • Adjust projectile behavior and effect timing directly in the editor.

  • Projectile trajectories are visual approximations, not gameplay physics simulations.

Character & Scene Setup

  • Stage up to 4 characters, each with 2 attached props (12 total slots).

  • Configure independent mesh attachments and transforms.

  • Position characters, props, and VFX spawn points using viewport gizmos.

  • Evaluate cloth simulation during animation playback.

Effect Adjustment & Iteration

  • Adjust supported Niagara parameters while previewing effects.

  • Refine VFX timing and placement without repeatedly entering Play Mode.

  • Preview VFX, audio, and camera shake events together.

Presets & Animation Notifies

  • Save and load configurations, tracks, timing, and transforms.

  • Reuse saved setups across working sessions.

  • Export supported VFX and sound events as Anim Notifies to animation assets.

Who It's For

Designed for VFX artists, animators, technical artists, and designers who need to evaluate animation-driven effects efficiently in Unreal Engine.

Whether you're developing combat effects, testing projectile behavior, synchronizing animation events, or refining complex VFX sequences, Previewer provides a dedicated environment for faster iteration.
