Ultimate Level Design Kit - Build a small blockout

Place and shape a platform

Selected ramp face and real Level Design mode controls — Historical native Unreal demonstration. Open the full-size frame to read the controls; this is not a new release acceptance capture.

Open Select Mode → Level Design, choose Shapes → Box, move the cursor over a blocking surface and click to place.
Select the box and set Dimensions to X 400, Y 300, Z 40 cm. These are example values. Keep the whole platform visible as the mesh updates.
For a room or container variant, enable Is Hollow and adjust Hollow Thickness. Inspect the interior and openings before using the shape in a traversal route.
In face editing, select a face and press Space to open the operation menu. Choose a supported operation and drag its handle. Check the complete result; use editor Undo to compare the previous state.

Repeat the layout

Choose Utilities → Copy. Click a source actor; use Ctrl + Click to add or remove sources, then press Enter to confirm the selection.
Set Output Mode = Copy, Copy Count = 3 and Translation Offset = (450, 0, 0) cm. Inspect all preview outputs, then click to commit them.
Use Output Mode = Instance when later source property edits should propagate to the repeated actors. Edit the original Dimensions and compare the linked results. Current instance output consists of independent level actors; location and rotation remain independent.
Choose ordinary Copy when each result should be independent. Deleting an Instance source also removes its linked instances; deleting one linked instance only removes that instance.

Check scale and surface appearance

Native cylinder material slots and per-slot UV controls — Historical native Unreal demonstration. Open the full-size frame to read the controls; this is not a new release acceptance capture.

Choose Measure, place points across a passage or gap, then press Enter to finish. Read Measure Unit and the distance display before judging traversal scale.
Select a placed shape and assign Material Slot 0. Adjust UV Scale, UV Tiling or UV Rotation Degrees while watching a recognizable grid or texture.
Enable Use UV Material Slot only for a per-section adjustment. Choose the existing UV Material Slot, change its UVs, then switch slots to check that the others retained their values.
Save your level and inspect the whole blockout. For a path-based layout, choose Spline Path, set Spline Type = Road, draw the path and press Enter to confirm; then compare Road Width and the visible ribbon.

External mesh placement, fence, spline-mesh and custom-material workflows require the corresponding source assets. A placed procedural actor remains editable; this workflow does not demonstrate a standalone mesh export.
