HDR Light Studio currently supports ASCII characters only in file paths.
If your Windows account username contains none ASCII characters, you will need to set the following Environment Variables to choose a location without none ASCII characters in the path.
Then HDR Light Studio will function correctly.
Instructions on how to add Environment Variables can be found on this page, showing how to set them up for Logging, but the same process can be used for all the environment variables below.
The HDR Light Studio user directory by default contains folders containing these files that HDR Light Studio needs: license files, presets, user presets, presets cache and favorites preset settings file.
With a default installation this path will be, for example on Windows: C:\Users\Username\AppData\Local\lightmap
If you wish to store these files in a different location, you can set the environment variable HDRLS_USER_DIR.
HDRLS_USER_DIR = \DiskName\HDRLS_DATA\USER\
When using HDR Light Studio, it create's temporary files shared with your 3D software, and temporary files during rendering.
With a default installation this path will be, for example on Windows: C:\Users\Username\AppData\Local\Temp\
Files will be created within subfolders in that location, for example all temp image files are stored in: HdrlsBuckets_Lightmap Ltd
If you wish to store these files in a different location, you can set the environment variable HDRLS_TEMPRENDER_DIR.
HDRLS_TEMPRENDER_DIR = \DiskName\HDRLS_DATA\TEMP\
