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, simple world-space helpers, 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.

Choosing an API

Use HUD and World Renderers when your client script needs to draw every frame. Use Item Render Markers when a server script wants clients to see a temporary item model in the world without spawning a real entity. Use Post Effects for screen-wide visual states such as blur, tint, grayscale, or custom shader passes.
