Block Outline Customizer

Block Outline Customizer 1.4.0

New

• Completely new config screen — dark, tabbed layout (Outline / Fill / Effects / General) with a live preview: opened in-game, the real outline updates as you drag; opened from the menu, a preview cube shows your style
• Outline styles: Full, Corners only, or Dashed
• Moving outline — the dashed style can march around the block, with adjustable speed
• RGB from corner — gradient mode that flows the colors across the block instead of one uniform color
• Custom RGB colors — pick up to 10 colors for the RGB cycle instead of the full rainbow (leave empty for classic rainbow)
• Presets — Classic, Neon, Subtle and Rainbow built in, plus a slot to save your own
• Per-block / per-tag overrides — give specific blocks or tags (e.g. #c:ores) their own style via the config file
• Shader fix option — makes the width slider work when a shader pack overrides the line renderer (use when shaders are on)
• Hex color input with color swatch next to the RGB sliders
• Translations: English, French, German, Spanish, Portuguese (BR), Russian, Chinese (Simplified)
• ModMenu integration (Fabric) and mods-list Config button (Forge/NeoForge)

Changed

• One unified JSON config (config/blockoutlinecustomizer.json) shared by all loaders — your old settings are migrated automatically
• The mod now fully replaces the vanilla outline renderer instead of restyling it — cleaner and more consistent
• Default keybind to open the config is U
• License changed to MIT

Fixed

• Outline width slider had no visible effect (it now controls real line thickness)
• Outline lines could thin out or vanish at certain camera angles
• RGB animation could stutter/snap periodically
