⚙️ 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

[Example]

⚠️ 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
