A render doesn't line up

Find out why a render sits crooked on the model, and how to fix its heading, position or the model.

ArchviewVR paints each render onto your proxy model from its camera point. If the render, the camera point or the model disagree, you see it in the tour.

Symptoms

• Door frames and wall corners in the render don’t sit on the model’s edges.
• The whole view looks turned, so walls seem to slide as you walk.
• Things double up or jump as you glide from one render to the next.

To check, open the project page and tick Model edges under the preview. See Check tools on the project page.

1. The heading is wrong

The most common cause. The render is in the right place but turned. The edges match the room’s shape, just rotated around you.

Fix it while uploading. Renders ArchviewVR isn’t sure about are marked Check on the check step. Press Use shared, Keep or Looks right, or drag the Heading slider until the edges sit on door frames and corners. See Check and fix flagged renders.

Fix a saved render.

1. **On the project page press Replace renders.**
2. Drop that render again. Same name, so it replaces itself and keeps its room name and stats.
3. **Open the All tab** on the check step and select the render.
4. **Drag the Heading slider** until the edges line up, then press Accept and save.

Tip: ArchviewVR matches headings most reliably when all your cameras face the same way. See Placing and naming cameras.

2. The render is in the wrong place

If no heading lines it up, the camera point is off. The edges look shifted, bigger or smaller, not just turned. Usually:

• The model moved after you exported the points, or was exported in different units from the cameras.
• The points file is old. A camera moved after the export.
• The render came from a different camera. Two renders matched to one camera land in the same spot. See Camera names don’t match.

Export the points (and the model, if it moved) again, then press Replace renders and drop the points file with the renders it names. New positions are used for every render in that file. See Making a simple proxy model.

3. The render isn’t a clean 360

• Not 2:1. The Renders step says not 2:1. These renders are still used but can’t line up. Re-render them at exactly 2:1. See Rendering 360° with Corona.
• Tilted camera. A camera with any tilt or roll can’t line up at every angle. Level it in 3ds Max and re-render.

4. Furniture smears as you walk

This is normal. Loose furniture isn’t in the proxy model, so it’s painted onto the floor and walls behind it. It looks right when you stop at a render and stretches between renders. Big pieces that bother you, like a kitchen island, can go into the proxy model.
