STUDIO LUMINANT — COMPASS-STAR RELIEF PANEL
SketchUp / visualization package (Tier 1 BIM content)
==============================================================

WHAT THIS IS
------------
A lightweight, render-ready 3D model of the Compass-Star relief panel for
architects to drop into design models (SketchUp, plus Rhino / 3ds Max / Enscape
/ V-Ray / Blender via the .obj or .glb). The relief is real displaced geometry,
so it holds up when orbited and lit. Custom sizes and patterns are made to order
— this tile is a representative 500 x 500 mm module.

NOTE: A native SketchUp .skp can only be written by SketchUp itself. To create
one: open SL_Compass-Star_500x500.dae in SketchUp Pro (File > Import > COLLADA),
then File > Save As .skp. The .dae imports with geometry, UVs and the default
finish already applied.

HOW TO USE IN SKETCHUP
----------------------
1. File > Import > select SL_Compass-Star_500x500.dae (set units = millimetres).
2. The panel lands as a component, 500 x 500 mm, 38 mm deep, finished in Bisque.
3. To change colourway: paint the face with the Clay or Obsidian albedo
   (Materials > Browse > textures/), or just set a solid SketchUp colour.
4. Array the component to fill a wall (tiles abut edge-to-edge on a 500 mm grid).


SPECIFICATION (provisional — confirm against physical sample before issuing)
---------------------------------------------------------------------------
Product            Compass-Star relief panel
Material           Lumina PMAG cast gypsum
Finish             Artisan finishes (Bisque / Clay / Obsidian shown)
Module size        500 x 500 mm
Panel depth        38 mm (10 mm backing slab + 28 mm relief)
Mounting           Adhesive-mount to sound, flat substrate
                   (primary adhesive: Soudal Fix-All High Tack)
Supply basis       EXW Sapanca. Installation available, quoted separately per
                   project.
Weight             TO BE CONFIRMED — weigh a physical sample. The supplied model
                   is a solid block for visualization only; do NOT derive weight
                   from its volume (that overstates it). Use the real sample
                   figure for substrate/structural sign-off, never the model.

TERMINOLOGY (architect-facing — keep these rules in any spec text)
  - Material = Lumina PMAG / PMAG by name. Finish term = "artisan finishes".
  - Refer to surface finishing only as "artisan finishes" — do not name the
    finishing chemistry, finishing products, chemical-supplier names, or SKUs.
  - No fire-performance claims of any kind until further notice.


FIDELITY NOTE
-------------
Geometry is a clean analytic reconstruction of the Compass-Star form (four
quadrant domes + raised four-point star), not a scan of a cast piece. It is
intended for design visualization, not fabrication. The casting/CNC master
comes from the production relief pipeline, not this file.
