### **Color Mask**

**`#cc [color]`**

**Example:** `//replace #color[lime] #color[red]`

***

### **Angle Mask**

**`#arcangle [minAngle] [maxAngle] [range]`**

**Example:** `//replace #arcangle[0][30][2] grass`

Use surface normal angle as the mask.

**minAngle / maxAngle:** 0 to 90 degrees (0 is fully horizontal)

**range:** distance that gets detected to get a smoother coverage (max = 2)

### **Proximity Mask**

**`#prox [mask] [distance]`**

replace blocks within distance to the mask on the Y-axis.

**Example:** `//replace #prox[wool][5] stone`

***

### **Proximity3D Mask**

**`#prox3D [mask] [distance]`**

replace blocks within distance to the mask.

**Example:** `//replace #prox3D[wool][5] stone`

***

### **Above Mask**

**`#above [mask] [distance]`**

**Example:** `//replace #above[wool][15] stone`

***

### **Below Mask**

**`#below [mask] [distance]`**

**Example:** `//replace #below[wool][5] stone`

***

### **YGradient Mask**

**`#ygradient <min> <max>`**

**Example:** `#ygradient[10][20]`

Min and max values are the Y coordinate.
