Triplanar 🌍

Triplanar mapping projects textures onto a mesh from three orthogonal planes (X, Y, Z axes), blending them based on the surface normals. This is useful for applying textures to complex geometry without explicit UV coordinates or for creating world-space texture effects. This effect requires a Depth Light.

Main Settings​

  • Style: Determines the source of the texture to be projected.
    • Disabled: No triplanar mapping is applied.
    • Still Image: Uses a single static texture (Triplanar Texture).
    • Animated Image: Uses an animated spritesheet (Triplanar Texture), controlled by GIF settings.
    • Colour: Projects a solid Colour instead of a texture.
    • Cells: Generates a procedural cell-like noise pattern.
  • Opacity: Controls the overall visibility of the triplanar-mapped texture/colour.
  • Apply: Determines how the projected texture/colour blends with the original screen colours.
    • 0 (Multiply): The triplanar texture/colour is multiplied with the screen.
    • 1 (Overlay): The triplanar texture/colour overlays the screen.
  • Scale: Adjusts the global tiling scale of the projected textures/patterns.
  • Triplanar Texture: (Active if Style is Still Image or Animated Image) The texture or spritesheet to be projected.
  • Colour: (Active if Style is Colour or used as a tint for textures) The colour to be projected or used to tint the projected texture.

Projection Controls​

  • Shift X, Shift Y, Shift Z: Offsets the texture projection along the world X, Y, and Z axes respectively.
  • Speed: (Vector XYZW) Controls the automatic scrolling speed of the projected textures along the X, Y, and Z axes. The W component is unused.
  • Opacity X, Opacity Y, Opacity Z: Controls the individual opacity or influence of the texture projected from the X, Y, and Z planes respectively. 1 is full opacity, 0 is transparent for that plane.

Distance & Falloff​

  • Distance Style: Determines how the triplanar effect fades with distance.
    • Everywhere: No distance-based fading.
    • Center: Fades based on distance from the object's center.
    • Linear Depth: Fades based on linear depth from the camera.
    • Radial Depth: Fades based on radial distance from the camera's view center.
    • Scanner: Creates a "scanner" effect, where the texture is only visible within a certain depth range defined by Distance and Fading.
  • Distance: The primary distance parameter for the selected Distance Style.
  • Distance Inverse: If enabled (greater than 0), inverts the distance-based fading effect (e.g., fades in instead of out).
  • Fading: Controls the softness or range of the distance-based fade.
  • Falloff Style: Enables a secondary, global falloff based on distance from the object running June.
    • Disabled: No global falloff.
    • Enabled: Uses Falloff Start and Falloff End to control a smooth fade.
  • Falloff Start, Falloff End: (Active if Falloff Style is Enabled) Defines the start and end distances for the global falloff.

Animation (for Animated Image Style)​

  • Gif Columns: The number of columns in the Triplanar Texture spritesheet.
  • Gif Rows: The number of rows in the Triplanar Texture spritesheet.
  • Gif Frames: The total number of frames in the spritesheet.
  • Gif Speed: The playback speed of the animated spritesheet. 0 for manual control.
  • Gif Scrub: Manually controls the current frame of the animation if Gif Speed is 0.

Additional Effects​

  • Border Power: If greater than 0, adds a border of Border Colour around the edges of the projected texture areas.
  • Border Colour: The colour of the border.
  • Rainbow Opacity: If greater than 0, applies a rainbow tint to the projected texture/colour.
  • Rainbow Controls: (Active if Rainbow Opacity > 0) Modifies the rainbow's speed, axis influence, and spread.
  • Distortion Power: Applies a wave-like distortion to the projected textures.
  • Distortion Speed: Controls the animation speed of the distortion.

Masking​

  • Mask Style: Enables texture-based masking for the triplanar effect.
    • Disabled: No masking.
    • Enabled: Uses Mask Texture to control visibility.
  • Mask Texture: The texture used to mask the triplanar effect. Typically, black areas in the mask will be transparent.
  • Invert Mask: If enabled, inverts the mask (white areas become transparent).
  • Mask Opacity X, Mask Opacity Y, Mask Opacity Z: Controls the opacity of the mask applied to each projection plane (X, Y, Z).
  • Mask Offset X, Mask Offset Y, Mask Offset Z: Offsets the mask texture sampling for each projection plane.
  • Mask Distortion: Applies a distortion effect to the mask texture itself.
  • Mask Fade: Controls the softness of the mask edges.
