Preview Aseprite Pixel Art with ShaderGlass

ShaderGlass can act as a shaded preview companion for pixel-art editors such as Aseprite; the source artwork stays unmodified.

Before you begin

Use Windows 10 version 2004 (build 19041) or Windows 11 and a DirectX 11-capable GPU. Confirm the source window or capture device works without additional post-processing. The exact labels can differ between ShaderGlass versions and operating modes.

Step-by-step workflow

1. Open a sample image or animation in Aseprite at a predictable zoom.
2. Use ShaderGlass to capture the relevant preview/window.
3. Compare CRT, LCD and softened previews against the unfiltered artwork.
4. Keep an unprocessed reference visible for judging real pixel colors.

Important details and limitations

The filter changes the preview, not the exported sprite PNG.

Use a clean reference when evaluating color values or palette constraints.

Shader distortion can reveal how artwork reads on a simulated display but should not replace testing on target hardware.

How to verify the result

Compare the processed scene with the same source shown without ShaderGlass. Watch for clipping, unexpected color changes, black regions and input lag. Keep one parameter fixed at a time while troubleshooting. For version-dependent settings, refer to the developer manual instead of relying on old screenshots.

Questions and answers

Does it export filtered sprites automatically?

No. The standard overlay displays a processed preview; it is not the source export pipeline.

Can it help assess pixel art?

Yes, it can approximate how sprite art might appear through different display types.
