Image Filter lets you use any texture as a mask. You can sample the image in grayscale, by a specific color, or by individual color channels (R, G, B, A). This makes it possible to paint custom spawn maps in any image editor and bring them directly into MegaWorld.

​
Settings

  • Blend Mode — how this filter combines with the previous mask in the stack. Multiply narrows the spawn area; Add expands it.
  • Image — the texture to use as the mask.
  • Filter Mode — which part of the texture to extract as the mask:
    • GrayScale — uses the overall luminance of the texture.
    • Color — masks based on similarity to a chosen color.
    • Red Channel — uses only the red channel.
    • Green Channel — uses only the green channel.
    • Blue Channel — uses only the blue channel.
    • Alpha Channel — uses only the alpha channel.
  • Color — the target color for color matching mode. Default is white.
  • Color Accuracy — how strictly the color must match. Higher values require a closer match; lower values allow more variation. Default is 0.5.
  • Offset X / Offset Z — UV offset to reposition the texture over the terrain.
