PortalFree library example · pixelfx by Patch
Not a flat image.
An effect built from parts.
Smith composes effects from kit components: flashes, shock rings, fire, smoke, sparks, embers, rocks and dust. Every part stays editable. Hide it, retime it, move it or resize it in the workspace, without spending credits.
The effect kit’s Explosion example, rendered live in your browser. Select a part to switch it off and on.
Ask for changes.
Every reply is a version.
Each project is its own conversation with Smith, so one effect’s history never leaks into another.
- Describe
- Write what the effect should do, or open any library effect as a starting point. Choose Standard, Enhanced or Ultra for the run.
- Refine
- Ask for a bluer ring, a shorter trail or a bigger blast. Each delivered version sits under the reply that made it, so you can compare and go back.
- Adjust
- Palette, hue, speed, timing, mirroring and every part are free to change. Only a new run from Smith uses credits.
- Keep
- Name, tag and favorite your results in My assets, and share projects with a team space.
Start from the library portal. Make it green and keep the drifting sparks.
Version 2 shifts the portal to green. Version 1 keeps the library colors.

Export a transparent PNG sprite sheet with Aseprite-style JSON, a PNG frame sequence or an animated GIF. Godot 4 users get a pack that works as soon as it is in the project.

The pixelfx library is free and MIT-licensed. Preview, recolor and download any effect without an account, or open one in the workspace and ask Smith to change it.
Pay for runs,
not for edits.
A run costs 5 credits on Standard, 15 on Enhanced and 40 on Ultra. It is charged only when Smith delivers a version; a failed run costs nothing.
Monthly credits refresh after each payment and do not roll over. Cancel future renewals anytime. Full pricing and credit rules
What can I create with VfxSmith?
Animated pixel art effects such as spells, explosions, sword slashes, projectile trails, pickups and weather. Start with a description or adapt an effect from the free library, then refine it with Smith.
Can I edit a generated effect?
Yes. Continue the conversation in the same project to request changes, or adjust colors, speed, timing and each part of the effect yourself. Saved versions stay in the project and in My assets.
Which files can I export?
Transparent PNG sprite sheets with animation JSON, PNG frame sequences, animated GIFs and Godot 4 packs with a ready scene and SpriteFrames. Read the sprite sheet guide for importing and timing.
Is the library free? How does AI usage work?

Standard, Enhanced and Ultra cost 5, 15 and 40 credits per run; failed runs are free.
