What this template includes

This overlay pack is built as a layer stack compatible with the Overlay Builder schema: gradients or shapes for background panels, text labels for status lines, optional webcam frames, and UI chrome that stays inside common platform safe margins. The preview image matches template-11.png.

Regarding What this template includes: For Alert Box — Classic Pulse, keep scenes simple while validating the core path, then add overlays and filters once the Stats dock stays clean.

Regarding What this template includes: Document the working profile name, encoder, canvas resolution, and capture method so you can restore them after an OBS or GPU driver update.

Regarding What this template includes: If behaviour changes after an update, launch Safe Mode to isolate third-party plugins, then re-enable modules one at a time.

Regarding What this template includes: Prefer wired ethernet for live streaming tests, and measure sustained upload with headroom rather than relying on a single speed-test spike.

Regarding What this template includes: When comparing settings, record short local samples with identical content so differences are visible without inventing synthetic FPS claims.

Regarding What this template includes: Keep browser sources and animated overlays modest; expensive HTML can raise rendering load even when the encoder itself is fine.

Regarding What this template includes: Match plugin builds to your OBS major version and architecture, and uninstall leftover DLLs from older major versions before reporting bugs.

Regarding What this template includes: Use Studio Mode when rehearsing transitions so you can preview the destination scene before it goes program.

Design intent

The layout emphasises readable type, restrained motion-friendly shapes, and empty regions for gameplay or camera content. Colours are high-contrast enough for small player windows without relying on busy textures that fight encoder bitrate.

Customisation tips

Duplicate the project in Overlay Builder, replace the sample text with your brand name, and adjust fill colours to match your palette. Keep critical HUD elements away from platform chat docks and mobile UI chrome.

Performance notes

Static PNG exports and simple browser-source packages are lighter than animated HTML with heavy scripts. Prefer CSS transforms over continuous high-resolution canvas animations when you need motion.
