Circle / Oval: Set width and height. Hit Generate. Each filled cell = place a block.
3D Shape: Pick a primitive (sphere, dome, box, cylinder, cone, pyramid, torus, ellipsoid), set Width × Depth × Height in blocks, optionally toggle Hollow for a 1-block shell. The slider browses layers from bottom to top — great for tile-building games where you stack each layer.
Image to Guide: Upload an image. Width sets the resolution; Ratio is either Auto (image's own aspect) or a preset (1:1, 4:3, 16:9 etc.) with Fit = Crop (centre-crop to fill) or Stretch (distort to fill). Depth > 1 turns brightness into a 3D heightmap, browseable layer-by-layer. Palette quantizes to a color set; each cell shows its real color. Remove BG drops transparent pixels and pixels matching the corners (Tol = how close the match must be). Threshold sets the brightness cutoff for empty/filled in 2D mode. Invert flips the mask or heightmap direction.
