| Octree generation failed | |
| 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. |
| Error opening meta file for writing | You may receive this message when antivirus software packages block the operations of NUBIGON while opening point clouds for the first time. We experienced this issue with the Avast antivirus software. We recommend whitelisting our software to resolve the issue. |
| Warning: Node filename exceeded maximum allowed length | It typically indicates that the dataset has (1) outliers far away from the rest of the dataset or (2) a lot of duplicate points. To fix the first issue, please apply a bounding box cleaning in your registration software before opening the point cloud in NUBIGON. To resolve the second issue, simply leave Remove duplicates in the Octree Generation Settings dialogue checked. |
