Screen Transitions - 120 Masks & One-Line Scene Loader (Unity, Godot 4, Ren'Py)

NEW in 1.1 (November 2026): RPG Maker MZ plugin. Hooks our masks into MZ's own fades: map transfers, battle start and end, title / load / game over and the Fadeout / Fadein Screen commands; the same mask covers and reveals. Plugin commands: Set Transition, Next Transition (once), Cover Screen, Reveal Screen. All 120 masks re-rendered at 816x624 and 1280x720. MZ only (MV uses older PIXI).

Screen transitions that open in your engine and just work. 120 grayscale masks generated by our own code and a small, tested runtime that turns any of them into a screen transition or a scene change with a loading bar - for Unity, Godot 4 and Ren'Py in one purchase.

Want to try it first? Screen Transitions Lite is free: 12 masks with the same API.

What you get

• 120 masks in 12 sets: iris, wipes, doors, blinds, grids and diamonds, radial and clock, spirals, shapes (star, heart, keyhole, hexagon...), pixel dissolves and Bayer dither, noise (Perlin, Voronoi, smoke, burn), a fantasy set (rune circle, ink blot, curtains, scroll, leaves, snow, sparkles, portal) and waves.
• Every mask as 1920x1080 16-bit, 2048x2048 16-bit and 256x256 8-bit for pixel art, plus Gallery.html with an animated GIF of every mask and masks.csv.
• Unity package (2022.3 LTS and Unity 6): one UI shader, ScreenTransition API, 124 presets, demo scenes, Preview Window, tests, PDF guide.
• Godot 4 addon: autoload ScreenTransition, awaitable API, signals, presets as text .tres, demo project, headless tests.
• Ren'Py file: every mask as st_<name> and st_<name>_cover, demo project.

Downloads: Unity ZIP, Godot 4 ZIP, Ren'Py ZIP and a separate ZIP with all mask PNGs.

Start in 60 seconds

1. Import the package (Unity), copy the addon (Godot) or the .rpy file (Ren'Py).
2. Open the demo - it plays every transition one after another.
3. Change scene with one line:
   ScreenTransition.LoadScene("Level2", preset);
await ScreenTransition.change_scene("res://level_2.tscn", "iris_circle_close")
scene bg castle with st_fantasy_ink_blot

Built for the problems buyers report

• No URP trouble. The transition is drawn as a top UI overlay, not a camera effect, so it works in Built-in, URP, HDRP, the 2D Renderer and Unity 6 - no Renderer Feature, no pink materials.
• Covers your UI. The overlay sits on sorting order 32000 (Godot: CanvasLayer 128), above Screen Space - Overlay canvases. Configurable.
• Times in seconds, easing curves, unscaled time (works in pause menus).
• Works in builds, not only in the Editor. A scene missing from Build Settings gives a clear warning in the Editor instead of failing silently later.
• Light on phones. One draw call and a short fragment shader; the overlay is switched off when idle.
• Easy setup. Nothing to add to your scene; the manager creates itself.
• Real loading progress with a minimum display time, so short loads never flicker.
• Events / signals for every phase and input blocking while the screen is covered.
• Pixel-art mode (big transition pixels + Bayer 4x4/8x8), glowing edges, colour or texture fill, cross-fade from the old scene through any mask, UI panel transitions (Unity).
• Bring your own mask: any grayscale image becomes a transition.

Technical details

• Unity 2022.3 LTS or newer (tested in 2022.3.62f3: 9 edit-mode + 6 play-mode tests; also imported and tested in Unity 6000.6 with URP). Requires Unity UI (uGUI). Masks import as R16 on desktop and R8 + dither on mobile/WebGL.
• Godot 4.3+ (tested on 4.7, Compatibility and Forward+, 34 headless tests). Godot imports PNG as 8-bit, so the Godot masks keep 16 bits in two channels and the shader joins them.
• Ren'Py 8.1+ (tested with 8.5.3: lint and a run through all 120 transitions).

FAQ

Can I use my own masks? Yes, any grayscale image (black first, white last).
Is there a free version? Yes - Screen Transitions Lite with 12 masks and the same API.
GameMaker? Not yet; version 1.1 added an RPG Maker MZ plugin. The masks are plain PNGs, so they work in any engine with a threshold shader.

How it was made

The masks and the demo art were generated by our own code (geometry, distance fields and noise) - no generative AI images. The C#, GDScript, shader and Ren'Py code and these texts were written with the help of an AI assistant (Claude) and tested in the engines listed above.
