Rendering

WARNING

Rendering is available on Fabric and NeoForge clients only. Paper is a server-only platform and does not support client-side rendering.

Katton's client rendering APIs cover frame callbacks, HUD drawing, world-space helpers, camera scenes, server-driven item markers, and full-screen post effects.

Entity renderers are documented with registration because they belong to the custom entity pipeline. See Registry / Entity Tutorial and the EntityRenderer API for model layers, animated entity renderers, and keyframe callbacks.

HUD and World RenderersDraw text, rectangles, textures, and world-space debug lines every frame.Item Render MarkersShow lightweight client-side item models in the world from server scripts.Post EffectsRegister, activate, and clear full-screen shader effects.Camera ScenesCompose camera paths, particles, geometry, and server-triggered timelines.

Choosing an API

Use HUD and World Renderers when a client script must draw every frame. Use Camera Scenes for camera control, particles, geometry, and timelines. Use Item Render Markers when a server script must show a temporary item model without a real entity. Use Post Effects for screen-wide blur, tint, grayscale, or custom shader passes.
