Specifically can a .XYZ point cloud file from Matterport be read/imported/used (?) by Scan Essentials in SketchUp Studio?
“A variety of file types are supported such as RWP, LAS/LAZ, E57, TZF, and PLY.”
It seems that third party converters are available to convert xyz to one of the formats accepted by Scan Essentials. Undet might be able to import it directly.
