Fix for PATH TOO LONG… Warning during installation Or Radiance not installed error during conversion
- The warning is caused due to the Path System variable being too long.
- The installation is successful but the path needs a manual fix.
- The fix is to manually add the radiance install folder to the environment variables
- Search for Edit the System Environment Variables on Windows Search bar
- Press Environment Variables button
- Find the Path entry on the System variables list
- Edit and add C:\Program Files\Radiance\bin to the end of the list if it doesn’t exist already
- Add a new entry for RAYPATH with C:\Program Files\Radiance\lib;.
- Press Ok. Ok
- Open command prompt and type oconv
(Should get the below message if the path is set correctly)
#?RADIANCE oconv FORMAT=Radiance_octree
