Preview

The right-hand preview shows the active build output or a selected node result.

  • Height shows normalized elevation as grayscale.
  • Material shows the evaluated Roblox terrain materials using representative colors.
  • Slope shows steepness for diagnosing cliffs and material thresholds.
  • 3D Mesh toggles an orbitable 32 × 32 surface preview with the map's real Width, Depth, Maximum height, and Sea level proportions.

Drag the 3D preview to orbit and scroll to zoom. The timing line reports evaluation time and evaluated node count. Errors appear below or over the preview and normally identify the node or missing input involved.

Preview resolution cycles through 64, 128, 256, 512, and 1024 samples. Higher values reveal smaller features but use more time and memory. It does not alter build density, which is fixed to Roblox terrain's 4-stud voxel grid.

Selecting or editing a node may preview that node's output. The mask editor restores the chosen Height, Material, or Slope build channel behind its paint overlay.
