Hi Hamia, you will find the material library file at C:\DIVA\Daylight\material.rad. It is a text file, you can add as many custom materials here as you like following the Radiance format. There is a short description on creating your own radiance materials on our wiki. The names you give the materials in the description will then show up using the material component in grasshopper.

Hi Hamia,

First I would check over the video tutorials. If you have saved your rhino file with a name (no spaces) and run a daylight factor using the diva for rhino toolbar (the 1.9 version one- delete the old one), then you should have a folder with the needed analysis files here:

C:\DIVA\Temp\YOUR_RHINO_FILE

When you open grasshopper within the rhino file you are working with, it is checking this folder for the needed analysis files. These vary by the type of analysis, so check the "metric" panel on the component and select daylight factor. Let me know if this helps or if you are still getting the error even with the correct analysis files in the temp folder.
