Install Optional Dependencies

This addon uses Pillow to read the (missing) image sizes from disk - required by the MVE, the Open3D and the VisualSFM importer. Pillow is also used to compute the (missing) point colors for OpenMVG JSON files. Using Pillow instead of Blender’s image API significantly improves processing time. Furthermore, this addon uses Pyntcloud to import several point cloud formats such as .ply, .pcd, .las, .laz, .asc, .pts and .csv. For parsing .las and .laz files Pylas, Lazrs and Pyntcloud 0.1.3 (or newer) is required.

Option 2: Installation using the command line

In case the installation using the GUI does not work, it is possible to install the dependencies with the command line.
