When using the Octree Disk Implementation in Chunky for rendering large scenes, the generated temporary files are saved in the system's default temporary directory. This method works fine for smaller scenes, but the Disk Implementation is designed for handling scenes of practically unlimited size. In such cases, the size of the temporary files can become extremely large, especially when pushing Chunky to its limits.

This creates a potential issue for users who have a smaller SSD allocated just for their operating system, as these large temp files might exceed the available storage space. Additionally, if the temp directory is located on a HDD while the SSD is used for other storage purposes, it could lead to inefficiencies.

To mitigate this issue, it would be practical to allow users the ability to customize the storage location for these temporary octree files. This would help prevent storage capacity problems of any kinds.

Yes, it could also be possible to just point the system's default temp folder to somewhere else but this would probably be too hard for the average user or just not wanted since that would affect all temp files not just chunky's.
