Troubleshooting

A blue warning (SmartScreen) appears at launch

The app is not yet code-signed, so Windows may warn on first launch. Click "More info" → "Run anyway". Always download from the official distribution page.

A project won't open

• Read the error dialog. For corrupted files, the automatic backup <name>.ppl.bak sits next to the project — rename its extension to .ppl to return to the last saved state
• Files saved by a newer version cannot be opened by an older app — update

The app crashed or the screen broke

• If the error screen appears, "Reload" usually recovers. Your work is auto-saved as recovery snapshots (.ppl) in user_data/recovery/
• Crash details are logged to user_data/logs/crash/ — attach them when reporting

Everything is slow

• The diagnostics tab in the bottom status bar shows evaluation time, transfer sizes, and which nodes are heavy

• Effective fixes: disable node previews, reduce image sizes or frame counts, lower parameters on heavy nodes (blur family, raymarching)
• "Clear cache" releases a tab's memory

Assets or presets are missing

• Official presets (map assets, materials) are placed under user_data/ on first launch. If missing, check user_data/library/maps/ etc. in the distribution zip
• If you launch from a shortcut, make sure its "Start in" folder points at the app's install folder

Where the logs are

Still stuck?

• With an AI agent available: ask "referring to ai/manual/, solve ○○" and it will answer based on this manual
• Otherwise contact support via the distribution page, attaching crash logs and reproduction steps
