Viewport

The Viewport tab allows you to configure the visual display settings for Gaea’s 3D viewport. These options affect how terrains and masks are rendered during editing and previewing.

Antialiasing

• Options: None, 2x, 4x, 8x
• Improves the smoothness of edges in the viewport rendering.
• Higher values provide cleaner visuals but may reduce performance on lower-end GPUs.
• Default: 4x

Display Options

• Do not clear viewport when unselecting a node (Toggle)
  • When enabled, the last viewed terrain remains visible even when no node is selected.
• Show Grid (Toggle)
  • Displays a reference grid in the viewport for spatial orientation.
• Show Compass (Toggle)
  • Adds a small compass widget indicating cardinal directions.
• Show Base Marker (Toggle)
  • Shows a marker for the origin/base of the terrain.
• Conserve memory when displaying 4K terrains (Toggle)
  • Optimizes memory usage for high-resolution terrains (4K+).
  • Can reduce visual fidelity slightly to save RAM and GPU memory.

Background

• Color Picker
  • Sets the background color of the viewport.
  • Click the color box to select a custom color or press X to reset to default.

Mask Gradient

• Defines the color scheme used when displaying mask outputs in the viewport.
• Options:
  • Greyscale – Black-to-white gradient. (Default)
  • Red – Red intensity map.
  • Blue – Blue intensity map.
  • Spectrum – Multi-color gradient for better visual separation of mask values.

Notes

• For best performance, use 2x or 4x antialiasing on mid-range GPUs.
• Enabling grid and compass can help with orientation but may add slight visual clutter.
• Conserving memory is recommended for projects with multiple high-resolution terrains or limited VRAM.
