Get your model ready to walk

vr-tecture lets visitors walk on your floors and stops them at your walls, at eye height. A few minutes spent on these points before exporting saves most problems later.

Floors, walls and ceilings

• Every walkable area needs a floor. Visitors stand on the surface below them. A room with no floor face, or a floor with a hole, is a place they cannot go.
• Walls stop visitors. Any surface in the way blocks them, so doorways need a real opening, not a wall with a door drawn on it.
• Steps up to about 30 cm are climbed. A normal stair (risers around 15 to 20 cm) works. A step higher than that is treated as a wall.
• Keep the ceiling. From inside, a room without a ceiling looks unfinished, and the sky shows through.
• Glass: model windows with a glass material so the outside shows. Visitors are stopped by glass like by a wall.

Scale and position

• Model in real units. GLB files are read in metres; for other formats the studio asks which unit you used and shows the size it reads.
• Keep the model near the origin and upright. If a converted model arrives on its side, tick It is lying on its side: stand it upright in the size check.
• Visitors see the space from 1.6 m above the floor, a standing adult’s eye height.

Weight

A lighter model opens faster, especially on phones and in headsets. The studio optimizes every upload, and each model can be up to 40 MB after that. If yours is heavy:

• Delete what is never seen: the outside of the building from an interior tour, other floors, hidden furniture, the inside of cabinets.
• Replace very detailed furniture (thousands of polygons per chair) with simpler versions. Detail closer than a visitor can walk is wasted.
• Use textures no larger than 2048 × 2048 pixels; 1024 is plenty for most surfaces.
• Use one model per style. If two styles share a room and differ only in finishes, use one model with Finishes or client choices instead of two uploads.

Names

• Name surfaces plainly (Floor, Wall, Worktop, Oak) so Suggest finishes can recognise them.
• Name interchangeable items Slot = Option, for example Sofa = Linen* and Sofa = Leather. See Let clients swap furniture and fixtures.

Check it in the tour

After saving, open the tour and walk every room once. Double-click (or double-tap) the floor to jump, try the doorways, and check that you cannot leave the building. Then set the start point. See Start point, stops and the guided tour and, if something is off, A tour is slow or does not open.
