When creating scans that are to be viewed on the HoloLens 2, there are some technical limitations to the size and complexity that should be considered. Some of these can be addressed in the software (see below), but some may require post-processing of your model to decimate it to a usable size. Here are the factors to keep in mind:
- Polygon count: Ideally around 200,000 and no more than 250,000 polygons per model.
- Texture size: 4K maximum (4096 x 4096 pixels).
- File size of OBJ: an approximate maximum size of 20-30 MB.
If your scan settings (quality, accuracy, scan area, etc.) create a model outside of these parameters, you can use software such as CloudCompare (https://www.danielgm.net/cc/) or MeshLab (https://www.meshlab.net/) to resize and decimate your model to a more appropriate size.
