⚙️ Configuration Guide

Spectrum Outline EntzuMC

All visual effects can be customized directly inside the shader files.

No extra mods or menus required — just edit a few lines.

---

📂 Where to edit

Open the pack and go to:

assets/minecraft/shaders/core/

You will find:

- `rendertype_lines.vsh` - `rendertype_lines.fsh`

At the top of both files you will see the configuration panel.

---

🎮 Changing the Mode

Find this line in both files:

#define MODE RAINBOW_LOOP

Replace `RAINBOW_LOOP` with one of these:

- `VANILLA` → Default Minecraft outline - `RAINBOW_FADE` → Smooth animated color shift - `RAINBOW_LOOP` → Colors travel around the edges - `CUSTOM` → Uses your selected color

⚠️ The mode must match in both files.

---

📏 Changing the Thickness

In `rendertype_lines.vsh`:

#define THICKNESS 2.5

Examples: - `1.0` → vanilla - `2.0` → slightly thicker - `3.0` → bold - `4.0+` → very thick

---

🎨 Custom Color Mode

If you use:

#define MODE CUSTOM

Change this in `rendertype_lines.fsh`:

#define CUSTOM_COLOR vec4(0.2, 0.8, 1.0, 1.0)

Format: vec4(R, G, B, A)

Values go from 0.0 to 1.0.

Examples:

White: vec4(1.0, 1.0, 1.0, 1.0)

Red: vec4(1.0, 0.0, 0.0, 1.0)

Purple: vec4(0.7, 0.2, 1.0, 1.0)

---

🌈 Changing Rainbow Speed

#define SPEED 2000.0

Higher = faster Lower = slower

---

🔁 Direction

#define DIRECTION 1.0

- `1.0` → normal - `-1.0` → reverse

---

🎚 Smooth Transitions

#define SMOOTH true

- `true` → soft gradient - `false` → hard color steps

---

💡 Tips

✔ Restart Minecraft after editing ✔ Use CUSTOM mode for quick testing ✔ If nothing changes → make sure both files match

Enjoy your personalized outlines 🔥
