Sorry for this. At what point did your game crash? Maybe you created too many points.
Seems to be the case. After the first crash I was more circumspect with using the LIDAR, which I could do because I remembered the layout from before the crash so I could walk around blind. Past the first door the level is just so huge I doubt I could keep myself using less than a dozen scans. I doubt it's your fault, more likely some limitation with either Unity or my video card drivers.
