About this Mod
Crystal Glow
Does not work with crystal opacity as it does what that mod does built into this one.
Crystal Glow is a client-side (Obv) mod that lets you customize end crystals with glow, bloom, glints, End Gateway overlays, Nether Portal overlays, opacity controls, and separate settings for the crystal core and glass. You can make the core bright and magical, make the glass more subtle, add soft bloom around the crystal, or give crystals a custom animated look without needing a shader loader.
The biggest thing with this mod is that it works with Vulkan Mod, so you can use crystal glow and bloom while playing with Vulkan instead of only normal Minecraft rendering. It also works without Vulkan incase you just prefer the mod normally, and it is made to be optimized with cached bloom, and lots more of other optimizations so you can keep the fps very high.
The mod also supports custom glint PNGs, so you can drop your own textures into the Crystal Glow glints folder, rescan them in game, and use them for the crystal core or glass. Core and glass settings can be linked together or customized separately depending on how much control you want.
This mod does NOT require any shader loader/iris/sodium. It works fully by itself and does not affect your whole game with shader effects.

Settings / Features List
| Section | Settings | What it does |
|---|---|---|
| General | Enabled, Menu Scale, Linked Glint Textures | Lets you turn Crystal Glow on or off, adjust the config screen scale, and decide if the core and glass should share the same glint texture. |
| Crystal Opacity | Opacity Enabled, Core Opacity, Inner Glass Opacity, Outer Glass Opacity, Extra Glass Opacity | Lets you control how transparent different crystal parts are instead of forcing the whole crystal to use one opacity value. |
| Core Glint | Core Glint Enabled, Glint Texture, Glint Visibility, Glint Speed, Glint Zoom | Controls the animated glint effect on the crystal core, including which texture it uses and how strong or fast it appears. |
| Glass Glint | Glass Glint Enabled, Glint Texture, Glint Visibility, Glint Speed, Glint Zoom | Controls the animated glint effect on the crystal glass separately from the core so the outside can look softer, cleaner, or completely different. |
| End Gateway Effect | Core/Glass End Gateway Enabled, Background Visibility, Overlay Visibility, Speed, Zoom, Bloom | Adds an End Gateway style animated shader effect to the crystal core or glass, with separate controls for visibility, movement, scale, and bloom. |
| Nether Portal Effect | Core/Glass Nether Portal Enabled, Background Visibility, Overlay Visibility, Speed, Zoom, Bloom | Adds a Nether Portal style animated shader effect to the crystal core or glass, with its own visibility, speed, zoom, and bloom behavior. |
| Bloom | Natural Core Bloom, Glint Bloom, End Gateway Bloom, Nether Portal Bloom, Bloom Strength, Spread, Length, Length Strength | Controls which crystal effects create bloom and how far the glow spreads around the crystal while keeping the optimized internal bloom path. |
| Custom Glints | Open Glints Folder, Rescan Glints, Built-in Glints, External PNG Glints | Lets you use the included glint textures or add your own PNG files without editing the jar. |
| Performance | Bloom Caps, Effect Limits, Optimized Bloom Rendering, Cached Bloom Activity | Keeps the crystal effects lightweight by limiting unnecessary bloom work, caching what needs to render, and using optimized rendering paths during gameplay. |
| Vulkan Support | Vulkan Compatible Glow and Bloom Rendering | Built to work with Vulkan Mod while still supporting normal Minecraft and Sodium rendering. |
