How to create a metal perforated radiance material with LBT

I edit the new blacked.rad files into the “C:\ladybug\untitled\gridbased_imagelessglare\scene\extra”, following your screen (are the strings written correctly?)

Seems correct. As long as you edit the generated file called [insert_filename]_blacked.rad (and overwrite the file with your changes).

…after, I run the batch file “commands.bat” and re-run the RunRadiance, but the error remain. In practice the generated files are empty.

Sorry, I see I didn’t make it perfectly clear that you should NOT run “runRadiance”. So the process goes:

1. Write “runRadiance”.
2. Edit [insert_filename]_blacked.rad.
3. Run “commands.bat” manually by double-clicking the file.
   3.1. Optionally, add “pause” at the end of “commands.bat”. This will let the cmd window stay open after executing the Radiance commands so you can see if Radiance reports any errors.
   
4. Import the result files in Grasshopper manually instead of using the output of “runRadiance”.
