Most Matterport Spaces are just fine in virtual reality. However, if you know before scanning that it will be definitely be explored in virtual reality here's a few tips to get the best possible VR Space.
Key points to remember when scanning for VR:
Keep at least 3 ft (1 m) away from walls. Stay in the center of hallways and narrow rooms so users don't feel uncomfortable in VR.
It's okay to scan closer to walls or objects in order to gather more 3D data, just remember to disable these spots in Matterport Workshop later.
Scan in front of doorways and just past them so you can move around the space. Make sure you have scan points at intersections.
With virtual reality, it is VERY IMPORTANT that scan locations be in a line of sight from each other. If there is no clear line of sight then users cannot move to that spot when inside the Space.
Scan locations should be 5 to 8 ft (1.5 to 2.5 m) apart. For very large areas, scan in a grid-like pattern as much as possible.
It's always helpful to scan more than necessary to gather more 3D data. Just remember to disable these scan locations in Matterport Workshop later. Final scan positions should be consistently spaced to produce a natural feeling of movement when exploring.
Keep the camera at the same height (eye level, about 5'6" or 167 cm) and do not move doors or other objects while scanning. Doors that are open in one scan and closed in another can cause VR artifacts. Place the camera where a normal visitor would naturally stand within the space.
Mark windows and mirrors immediately and adjust markings after every scan. This improves alignment, only does this improve alignment, models with improperly or unmarked windows and mirrors will not look that good in stereoscopic mode.
Capture complete rooms. If capturing open areas or parts of rooms, scan farther than you want users to walk. Later on disable these spots in Matterport Workshop beyond your desired boundary. Users won't walk there but you can keep 3D data gained from scanning there.
Finally, remember these are guidelines and not hard rules. You may need to get a scan that is less than 3 ft (1 m) away from a wall, or scans in some rooms will be unevenly spaced. Navigation and easy user navigation is your goal.
To scan the top of a bar or a high table, it is a good idea to raise the tripod high above eye level up for another scan. Likewise, you may need to lower the tripod as low as it can go to fill in holes in the mesh. Just remember to disable these spots in Matterport Workshop since height transitions can feel unnatural.
