| Octree generation failed. One or more input point cloud files are probably corrupted. | One or more of your files are corrupted. Corrupted data usually has a small disk size. Make sure to use non-corrupted files for the octree generation. |
| You do not have enough disk space on the drive containing your temporary files folder | During octree generation, NUBIGON creates temporary files as big as the octree. Choosing a folder on a secondary drive for your temporary files will save space. You can also use an external disk if your computer does not have a secondary drive. |
| You do not have enough disk space on the drive containing your project folder | Generating an octree may temporarily require more than twice the disk space of your source files. Ensure you have enough disk space in the drive containing your NUBIGON project. |
